BACKGROUND

There is a significant unmet need for effective therapies, particularly prophylaxis therapies, for migraine. Results from multiple studies indicate that ˜14 million migraineurs in the US could qualify and benefit from an effective and safe preventive therapy. Currently approved migraine prophylactic therapies are only partially effective and have considerable side-effect profiles which significantly limit the acceptability of these medications. Despite these limitations, 4.5 million individuals with frequent migraine headache in the US take prophylactic medication for their migraines.

Pituitary adenylate cyclase-activating polypeptides (PACAP) are 38-amino acid (PACAP38), or 27-amino acid (PACAP27) peptides that were first isolated from an ovine hypothalamic extract on the basis of their ability to stimulate cAMP formation in anterior pituitary cells (Miyata, A., et al., “Isolation of a novel 38 residue-hypothalamic polypeptide which stimulates adenylate cyclase in pituitary cells.”, Biochem Biophys Res Commun. 1989; 164:567-574; Miyata, A., et al., “Isolation of a neuropeptide corresponding to the N-terminal 27 residues of the pituitary adenylate cyclase activating polypeptide with 38 residues (PACAP38).”, Biochem Biophys Res Commun 1990; 170:643-648). PACAP peptides belong to the vasoactive intestinal polypeptide VIP-secretin-hormone-releasing hormone (GHRH)-glucagon superfamily with the sequence of human PACAP27 shares 68% identity with vasoactive intestinal polypeptide (VIP) (Campbell, R. M. and Scanes, C. G., “Evolution of the growth hormone-releasing factor (GRF) family of peptides. Growth Regul.” 1992; 2:175-191). The major form of PACAP peptide in the human body is PACAP38 and the pharmacology of PACAP38 and PACAP27 has not been shown to be different from each other. Unless indicated otherwise herein, PACAP or PACAP38 will be used to represent PACAP38, and PACAP27 will be used to specify PACAP27.

Three PACAP receptors have been reported: one that binds PACAP with high affinity and has a much lower affinity for VIP (PAC1 receptor, or simply “PAC1”), and two that recognize PACAP and VIP essentially equally well (VPAC1 and VPAC2 receptors, or simply “VPAC1” or “VPAC2”, respectively) (Vaudry, D., et al. “Pituitary adenylate cyclase-activating polypeptide and its receptors: 20 years after the discovery.”, Pharmacol Rev. 2009; September 61(3):283-357).

PACAP is capable of binding all three receptors (PAC1, VPAC1, VPAC2) with similar potency and is thus not particularly selective. VIP, on the other hand, binds with significantly higher affinity to VPAC1 and VPAC2, as compared with PAC1. Maxadilan, a 65 amino acid peptide originally isolated from the sand-fly (Lerner, E. A., et al., “Isolation of maxadilan, a potent vasodilatory peptide from the salivary glands of the sand fly Lutzomyia longipalpis”, J Biol Chem. 1991 Jun. 15; 266(17):11234-6; Lerner, E. A., et al., “Maxadilan, a PAC1 receptor agonist from sand flies”, Peptides. September 2007; 28(9): 1651-1654.), is exquisitely selective for PAC1 compared with VPAC1 or VPAC2, and can thus be used as a PAC1-selective agonist.

The terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention, which is defined solely by the claims.

Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients or reaction conditions used herein should be understood as modified in all instances by the term “about.” The term “about” when used in connection with percentages means±10%.

Definitions

The term “polynucleotide” or “nucleic acid” includes both single-stranded and double-stranded nucleotide polymers. The nucleotides comprising the polynucleotide can be ribonucleotides or deoxyribonucleotides or a modified form of either type of nucleotide.

An “isolated nucleic acid molecule” means a DNA or RNA of genomic, mRNA, cDNA, or synthetic origin or some combination thereof which is not associated with all or a portion of a polynucleotide in which the isolated polynucleotide is found in nature, or is linked to a polynucleotide to which it is not linked in nature. For purposes of this disclosure, it should be understood that “a nucleic acid molecule comprising” a particular nucleotide sequence does not encompass intact chromosomes. Isolated nucleic acid molecules “comprising” specified nucleic acid sequences may include, in addition to the specified sequences, coding sequences for up to ten or even up to twenty other proteins or portions thereof, or may include operably linked regulatory sequences that control expression of the coding region of the recited nucleic acid sequences, and/or may include vector sequences.

Unless specified otherwise, the left-hand end of any single-stranded polynucleotide sequence discussed herein is the 5′ end; the left-hand direction of double-stranded polynucleotide sequences is referred to as the 5′ direction. The direction of 5′ to 3′ addition of nascent RNA transcripts is referred to as the transcription direction; sequence regions on the DNA strand having the same sequence as the RNA transcript that are 5′ to the 5′ end of the RNA transcript are referred to as “upstream sequences;” sequence regions on the DNA strand having the same sequence as the RNA transcript that are 3′ to the 3′ end of the RNA transcript are referred to as “downstream sequences.”

The term “control sequence” refers to a polynucleotide sequence that can affect the expression and processing of coding sequences to which it is ligated. The nature of such control sequences may depend upon the host organism. In particular embodiments, control sequences for prokaryotes may include a promoter, a ribosomal binding site, and a transcription termination sequence. For example, control sequences for eukaryotes may include promoters comprising one or a plurality of recognition sites for transcription factors, transcription enhancer sequences, and transcription termination sequence. “Control sequences” can include leader sequences and/or fusion partner sequences.

The term “vector” means any molecule or entity (e.g., nucleic acid, plasmid, bacteriophage or virus) used to transfer protein coding information into a host cell.

The term “expression vector” or “expression construct” refers to a vector that is suitable for transformation of a host cell and contains nucleic acid sequences that direct and/or control (in conjunction with the host cell) expression of one or more heterologous coding regions operatively linked thereto. An expression construct may include, but is not limited to, sequences that affect or control transcription, translation, and, if introns are present, affect RNA splicing of a coding region operably linked thereto.

As used herein, “operably linked” means that the components to which the term is applied are in a relationship that allows them to carry out their inherent functions under suitable conditions. For example, a control sequence in a vector that is “operably linked” to a protein coding sequence is ligated thereto so that expression of the protein coding sequence is achieved under conditions compatible with the transcriptional activity of the control sequences.

The term “host cell” means a cell that has been transformed, or is capable of being transformed, with a nucleic acid sequence and thereby expresses a gene of interest. The term includes the progeny of the parent cell, whether or not the progeny is identical in morphology or in genetic make-up to the original parent cell, so long as the gene of interest is present.

The term “transduction” means the transfer of genes from one bacterium to another, usually by bacteriophage. “Transduction” also refers to the acquisition and transfer of eukaryotic cellular sequences by replication defective retroviruses.

The term “transfection” means the uptake of foreign or exogenous DNA by a cell, and a cell has been “transfected” when the exogenous DNA has been introduced inside the cell membrane. A number of transfection techniques are well known in the art and are disclosed herein. See, e.g., Graham et al., 1973, Virology 52:456; Sambrook et al., 2001, Molecular Cloning: A Laboratory Manual, supra; Davis et al., 1986, Basic Methods in Molecular Biology, Elsevier; Chu et al., 1981, Gene 13:197. Such techniques can be used to introduce one or more exogenous DNA moieties into suitable host cells.

The term “transformation” refers to a change in a cell's genetic characteristics, and a cell has been transformed when it has been modified to contain new DNA or RNA. For example, a cell is transformed where it is genetically modified from its native state by introducing new genetic material via transfection, transduction, or other techniques. Following transfection or transduction, the transforming DNA may recombine with that of the cell by physically integrating into a chromosome of the cell, or may be maintained transiently as an episomal element without being replicated, or may replicate independently as a plasmid. A cell is considered to have been “stably transformed” when the transforming DNA is replicated with the division of the cell.

The terms “polypeptide” or “protein” are used interchangeably herein to refer to a polymer of amino acid residues. The terms also apply to amino acid polymers in which one or more amino acid residues is an analog or mimetic of a corresponding naturally occurring amino acid, as well as to naturally occurring amino acid polymers. The terms can also encompass amino acid polymers that have been modified, e.g., by the addition of carbohydrate residues to form glycoproteins, or phosphorylated. Polypeptides and proteins can be produced by a naturally-occurring and non-recombinant cell; or it is produced by a genetically-engineered or recombinant cell, and comprise molecules having the amino acid sequence of the native protein, or molecules having deletions from, additions to, and/or substitutions of one or more amino acids of the native sequence. The terms “polypeptide” and “protein” specifically encompass antibodies, e.g., anti-PAC1 antibodies (aka PAC1 antibodies), PAC1 binding proteins, antibodies, or sequences that have deletions from, additions to, and/or substitutions of one or more amino acids of an antigen-binding protein. The term “polypeptide fragment” refers to a polypeptide that has an amino-terminal deletion, a carboxyl-terminal deletion, and/or an internal deletion as compared with the full-length protein. Such fragments may also contain modified amino acids as compared with the full-length protein. In certain embodiments, fragments are about five to 500 amino acids long. For example, fragments may be at least 5, 6, 8, 10, 14, 20, 50, 70, 100, 110, 150, 200, 250, 300, 350, 400, or 450 amino acids long. Useful polypeptide fragments include immunologically functional fragments of antibodies, including binding domains. In the case of a PAC1-binding antibody, useful fragments include but are not limited to a CDR region, a variable domain of a heavy or light chain, a portion of an antibody chain or just its variable domain including two CDRs, and the like.

The term “isolated protein” (e.g., isolated antibody), “isolated polypeptide” or “isolated antibody” means that a subject protein, polypeptide or antibody is free of most other proteins with which it would normally be found and has been separated from at least about 50 percent of polynucleotides, lipids, carbohydrates, or other materials with which it is associated in nature. Typically, an “isolated protein”, “isolated polypeptide” or “isolated antibody” constitutes at least about 5%, at least about 10%, at least about 25%, or at least about 50% of a given sample. Genomic DNA, cDNA, mRNA or other RNA, of synthetic origin, or any combination thereof may encode such an isolated protein. Preferably, the isolated protein polypeptide or antibody is substantially free from other proteins or other polypeptides or other contaminants that are found in its natural environment that would interfere with its therapeutic, diagnostic, prophylactic, research or other use.

The terms “human PAC1”, “human PAC₁”, “hPAC1” and “hPAC₁”, “human PAC1 receptor”, “human PAC₁ receptor”, “hPAC1 receptor” and “hPAC₁ receptor” are used interchangeably and refer to the human pituitary adenylate cyclase-activating polypeptide type I receptor. hPAC1 is a 468 amino acid protein designated as P41586 (PACR_HUMAN) in the UniProtKB/Swiss-Prot database and is encoded by the ADCYAP1R1 gene. PACAP-27 and PACAP-38 are the principal endogenous agonists of PAC1. Unless otherwise specified or clear from the context in which the term is used, “PAC1” refers to human hPAC1.

A “variant” of a polypeptide (e.g., an antigen binding protein, or an antibody) comprises an amino acid sequence wherein one or more amino acid residues are inserted into, deleted from and/or substituted into the amino acid sequence relative to another polypeptide sequence. Variants include fusion proteins.

A “derivative” of a polypeptide is a polypeptide (e.g., an antigen binding protein, or an antibody) that has been chemically modified in some manner distinct from insertion, deletion, or substitution variants, e.g., via conjugation to another chemical moiety.

The term “naturally occurring” as used throughout the specification in connection with biological materials such as polypeptides, nucleic acids, host cells, and the like, refers to materials which are found in nature.

An antibody or antigen binding fragment thereof is said to “specifically bind” its target when the dissociation constant (K_(D)) is ≦10⁻⁶ M. The antibody specifically binds the target antigen with “high affinity” when the K_(D) is ≦1×10⁻⁸ M. In one embodiment, the antibodies or antigen-binding fragments thereof will bind to PAC1, or human PAC1 with a K_(D)≦5×10⁻⁷; in another embodiment the antibodies or antigen-binding fragments thereof will bind with a K_(D)≦1×10⁻⁷; in another embodiment the antibodies or antigen-binding fragments thereof will bind with a K_(D)≦5×10⁻⁸; in another embodiment the antibodies or antigen-binding fragments thereof will bind with a K_(D)≦1×10⁻⁸; in another embodiment the antibodies or antigen-binding fragments thereof will bind with a K_(D)≦5×10⁻⁹; in another embodiment the antibodies or antigen-binding fragments thereof will bind with a K_(D)≦1×10⁻⁹; in another embodiment the antibodies or antigen-binding fragments thereof will bind with a K_(D)≦5×10⁻¹⁰; in another embodiment the antibodies or antigen-binding fragments thereof will bind with a K_(D)≦1×10⁻¹⁰.

An antibody, antigen binding fragment thereof or antigen binding protein “selectively inhibits” a specific receptor relative to other receptors when the IC50 of the antibody, antigen binding fragment thereof or antigen binding protein in an inhibition assay of the specific receptor is at least 50-fold lower than the IC50 in an inhibition assay of another “reference” receptor, e.g., a hVPAC1 or hVPAC2 receptor. The “selectivity ratio” is the IC50 of the reference receptor divided by IC50 of the specific receptor. For example, if hPAC1 is the specific receptor and hVPAC1 is the reference receptor, and the IC50 of a particular anti-PAC1 antibody described herein against hPAC1 is 10 nm and against hVPAC1 is 10 μm, that particular antibody can be characterized as having a selectivity ratio of 1000:1 for hPAC1 relative to hVPAC1. IC50 is the dose/concentration required to achieve 50% inhibition (of a biological or biochemical function). With radioactive ligands, IC50 is the concentration of a competing ligand that displaces 50% of the specific binding of the radioligand. EC50 is the concentration or dose required to induce a response 50% of the maximum response.

Ki data are typically generated in the context of competition binding experiments, which are typically done by attaching a radioactive isotope (e.g., a ¹²⁵I) to an “agonist”. The experiments measure the binding of the agonist in increasing concentrations of an “antagonist”. Ki refers to the concentration of the “antagonist” or test compound, e.g., a test anti-PAC1 antibody, which would occupy 50% of the receptors if there was no radioligand present. Ki can be calculated using the equation Ki=IC50/(1+([L]/Kd)), where [L] is the concentration of the radioligand used (e.g., a ¹²⁵I-labeled PAC-1 antibody) and Kd is the dissociation constant of the radioligand. See, e.g., Keen M, MacDermot J (1993) Analysis of receptors by radioligand binding. In: Wharton J, Polak J M (eds) Receptor autoradiography, principles and practice. Oxford University Press, Oxford.

“Antigen binding region” means a protein, or a portion of a protein, that specifically binds a specified antigen. For example, that portion of an antibody that contains the amino acid residues that interact with an antigen and confer on the antibody its specificity and affinity for the antigen is referred to as “antigen binding region.” An antigen binding region typically includes one or more “complementary binding regions” (“CDRs”). Certain antigen binding regions also include one or more “framework” regions. A “CDR” is an amino acid sequence that contributes to antigen binding specificity and affinity. “Framework” regions can aid in maintaining the proper conformation of the CDRs to promote binding between the antigen binding region and an antigen.

In certain aspects, recombinant antibodies or antigen-binding fragments thereof that bind PAC1 protein, or human PAC1, are provided. In this context, a “recombinant protein” is a protein made using recombinant techniques, i.e., through the expression of a recombinant nucleic acid as described herein. Methods and techniques for the production of recombinant proteins are well known in the art.

The term “antibody” refers to an intact immunoglobulin of any isotype, or an antigen binding fragment thereof that can compete with the intact antibody for specific binding to the target antigen, and includes, for instance, chimeric, humanized, fully human, and bispecific antibodies or antigen-binding fragments thereof. An “antibody” as such is a species of an antigen binding protein. An intact antibody generally will comprise at least two full-length heavy chains and two full-length light chains, but in some instances may include fewer chains such as antibodies naturally occurring in camelids which may comprise only heavy chains. Antibodies or antigen-binding fragments thereof may be derived solely from a single source, or may be “chimeric,” that is, different portions of the antibody may be derived from two different antibodies as described further below. The antibodies or binding fragments thereof may be produced in hybridomas, by recombinant DNA techniques, or by enzymatic or chemical cleavage of intact antibodies. Unless otherwise indicated, the term “antibody” includes, in addition to antibodies comprising two full-length heavy chains and two full-length light chains, derivatives, variants, fragments, and mutations thereof, examples of which are described below.

The term “light chain” includes a full-length light chain and fragments thereof having sufficient variable region sequence to confer binding specificity. A full-length light chain includes a variable region domain, V_(L), and a constant region domain, C_(L). The variable region domain of the light chain is at the amino-terminus of the polypeptide. Light chains include kappa chains and lambda chains.

The term “heavy chain” includes a full-length heavy chain and fragments thereof having sufficient variable region sequence to confer binding specificity. A full-length heavy chain includes a variable region domain, V_(H), and three constant region domains, C_(H)1, C_(H)2, and C_(H)3. The V_(H) domain is at the amino-terminus of the polypeptide, and the C_(H) domains are at the carboxyl-terminus, with the C_(H)3 being closest to the carboxy-terminus of the polypeptide. Heavy chains may be of any isotype, including IgG (including IgG1, IgG2, IgG3 and IgG4 subtypes), IgA (including IgA1 and IgA2 subtypes), IgM and IgE. In one embodiment, the heavy chain is an aglycosylated IgG1, e.g., an IgG1 HC with an N297G mutation.

The term “signal sequence”, “leader sequence” or “signal peptide” refers to a short (3-60 amino acids long) peptide chain that directs the transport of a protein. Signal peptides may also be called targeting signals, signal sequences, transit peptides, or localization signals. Some signal peptides are cleaved from the protein by signal peptidase after the proteins are transported, such that the biologically active form of the protein (e.g., an antibody as described herein) is the cleaved, shorter form. Accordingly, terms such as “antibody comprising a heavy chain . . . ”, “antibody comprising a light chain . . . ”, etc., where the antibody is characterized as having a heavy and/or light chain with a particular identified sequence, are understood to include antibodies having the specific identified sequences, antibodies having the specific identified sequences except that the signal sequences are replaced by different signal sequences, as well as antibodies having the identified sequences, minus any signal sequences.

The term “antigen binding fragment” (or simply “fragment”) of an antibody or immunoglobulin chain (heavy or light chain), as used herein, comprises a portion (regardless of how that portion is obtained or synthesized) of an antibody that lacks at least some of the amino acids present in a full-length chain but which is capable of specifically binding to an antigen. Such fragments are biologically active in that they bind specifically to the target antigen and can compete with other antibodies or antigen-binding fragments thereof, for specific binding to a given epitope. In one aspect, such a fragment will retain at least one CDR present in the full-length light or heavy chain, and in some embodiments will comprise a single heavy chain and/or light chain or portion thereof. These biologically active fragments may be produced by recombinant DNA techniques, or may be produced, e.g., by enzymatic or chemical cleavage of intact antibodies. Immunologically functional immunoglobulin fragments include, but are not limited to, Fab, Fab′, F(ab′)₂, Fv, domain antibodies and single-chain antibodies, and may be derived from any mammalian source, including but not limited to human, mouse, rat, camelid or rabbit. It is contemplated further that a functional portion of the antibodies disclosed herein, for example, one or more CDRs, could be covalently bound to a second protein or to a small molecule to create a therapeutic agent directed to a particular target in the body, possessing bifunctional therapeutic properties, or having a prolonged serum half-life.

An “Fab fragment” is comprised of one light chain and the C_(H)1 and variable regions of one heavy chain. The heavy chain of a Fab molecule cannot form a disulfide bond with another heavy chain molecule.

An “Fc” region contains two heavy chain fragments comprising the C_(H)1 and C_(H)2 domains of an antibody. The two heavy chain fragments are held together by two or more disulfide bonds and by hydrophobic interactions of the C_(H)3 domains.

An “Fab′ fragment” contains one light chain and a portion of one heavy chain that contains the V_(H) domain and the C_(H)1 domain and also the region between the C_(H)1 and C_(H)2 domains, such that an interchain disulfide bond can be formed between the two heavy chains of two Fab′ fragments to form an F(ab′)₂ molecule.

An “F(ab′)₂ fragment” contains two light chains and two heavy chains containing a portion of the constant region between the C_(H)1 and C_(H)2 domains, such that an interchain disulfide bond is formed between the two heavy chains. A F(ab′)₂ fragment thus is composed of two Fab′ fragments that are held together by a disulfide bond between the two heavy chains.

The “Fv region” comprises the variable regions from both the heavy and light chains, but lacks the constant regions.

“Single-chain antibodies” are Fv molecules in which the heavy and light chain variable regions have been connected by a flexible linker to form a single polypeptide chain, which forms an antigen-binding region. Single chain antibodies are discussed in detail in International Patent Application Publication No. WO 88/01649 and U.S. Pat. No. 4,946,778 and U.S. Pat. No. 5,260,203, the disclosures of which are incorporated by reference.

A “domain antibody” is an immunologically functional immunoglobulin fragment containing only the variable region of a heavy chain or the variable region of a light chain. In some instances, two or more V_(H) regions are covalently joined with a peptide linker to create a bivalent domain antibody. The two V_(H) regions of a bivalent domain antibody may target the same or different antigens.

A “bivalent antigen binding protein” or “bivalent antibody” comprises two antigen binding sites. In some instances, the two binding sites have the same antigen specificities. Bivalent antibodies may be bispecific, see, infra.

A “multispecific antigen binding protein” or “multispecific antibody” is one that targets more than one antigen or epitope.

A “bispecific,” “dual-specific” or “bifunctional” antigen binding protein or antibody is a hybrid antigen binding protein or antibody, respectively, having two different antigen binding sites. Bispecific antibodies are a species of multispecific antigen binding protein or multispecific antibody and may be produced by a variety of methods including, but not limited to, fusion of hybridomas or linking of Fab′ fragments. See, e.g., Songsivilai and Lachmann, 1990, Clin. Exp. Immunol. 79:315-321; Kostelny et al., 1992, J. Immunol. 148:1547-1553. The two binding sites of a bispecific antigen binding protein or antibody will bind to two different epitopes, which may reside on the same or different protein targets.

The term “neutralizing antigen binding protein” or “neutralizing antibody” refers to an antigen binding protein or antibody, respectively, that binds to a ligand, prevents binding of the ligand to its binding partner and interrupts the biological response that otherwise would result from the ligand binding to its binding partner. In assessing the binding and specificity of an antigen binding protein, e.g., an antibody or immunologically functional antigen binding fragment thereof, an antibody or fragment will substantially inhibit binding of a ligand to its binding partner when an excess of antibody reduces the quantity of binding partner bound to the ligand by at least about 20%, 30%, 40%, 50%, 60%, 70%, 80%, 85%, 90%, 95%, 97%, 99% or more (as measured in an in vitro competitive binding assay). In the case of a PAC1 binding protein, such a neutralizing molecule will diminish the ability of PAC1 to bind PACAP, e.g., PACAP-27 or PACAP-38.

The term “antigen” or “immunogen” refers to a molecule or a portion of a molecule capable of being bound by a selective binding agent, such as an antigen binding protein (including, e.g., an antibody or immunological functional antigen binding fragment thereof), and additionally capable of being used in an animal to produce antibodies capable of binding to that antigen. An antigen may possess one or more epitopes that are capable of interacting with different antibodies or fragments thereof.

The term “epitope” is the portion of a molecule that is bound by an antigen binding protein (for example, an antibody). The term includes any determinant capable of specifically binding to an antigen binding protein, such as an antibody or to a T-cell receptor. An epitope can be contiguous or non-contiguous (e.g., amino acid residues that are not contiguous to one another in the polypeptide sequence but that within in context of the molecule are bound by the antigen binding protein). In certain embodiments, epitopes may be mimetic in that they comprise a three dimensional structure that is similar to an epitope used to generate the antibody, yet comprise none or only some of the amino acid residues found in that epitope used to generate the antibody. Most often, epitopes reside on proteins, but in some instances may reside on other kinds of molecules, such as nucleic acids. Epitope determinants may include chemically active surface groupings of molecules such as amino acids, sugar side chains, phosphoryl or sulfonyl groups, and may have specific three dimensional structural characteristics, and/or specific charge characteristics. Generally, antibodies specific for a particular target antigen will preferentially recognize an epitope on the target antigen in a complex mixture of proteins and/or macromolecules.

The term “identity” refers to a relationship between the sequences of two or more polypeptide molecules or two or more nucleic acid molecules, as determined by aligning and comparing the sequences. “Percent identity” means the percent of identical residues between the amino acids or nucleotides in the compared molecules and is calculated based on the size of the smallest of the molecules being compared. For these calculations, gaps in alignments (if any) must be addressed by a particular mathematical model or computer program (i.e., an “algorithm”). Methods that can be used to calculate the identity of the aligned nucleic acids or polypeptides include those described in Computational Molecular Biology, (Lesk, A. M., ed.), 1988, New York: Oxford University Press; Biocomputing Informatics and Genome Projects, (Smith, D. W., ed.), 1993, New York: Academic Press; Computer Analysis of Sequence Data, Part I, (Griffin, A. M., and Griffin, H. G., eds.), 1994, New Jersey: Humana Press; von Heinje, G., 1987, Sequence Analysis in Molecular Biology, New York: Academic Press; Sequence Analysis Primer, (Gribskov, M. and Devereux, J., eds.), 1991, New York: M. Stockton Press; and Carillo et al., 1988, SIAM J. Applied Math. 48:1073.

In calculating percent identity, the sequences being compared are aligned in a way that gives the largest match between the sequences. The computer program used to determine percent identity is the GCG program package, which includes GAP (Devereux et al., 1984, Nucl. Acid Res. 12:387; Genetics Computer Group, University of Wisconsin, Madison, Wis.). The computer algorithm GAP is used to align the two polypeptides or polynucleotides for which the percent sequence identity is to be determined. The sequences are aligned for optimal matching of their respective amino acid or nucleotide (the “matched span”, as determined by the algorithm). A gap opening penalty (which is calculated as 3× the average diagonal, wherein the “average diagonal” is the average of the diagonal of the comparison matrix being used; the “diagonal” is the score or number assigned to each perfect amino acid match by the particular comparison matrix) and a gap extension penalty (which is usually 1/10 times the gap opening penalty), as well as a comparison matrix such as PAM 250 or BLOSUM 62 are used in conjunction with the algorithm. In certain embodiments, a standard comparison matrix (see, Dayhoff et al., 1978, Atlas of Protein Sequence and Structure 5:345-352 for the PAM 250 comparison matrix; Henikoff et al., 1992, Proc. Natl. Acad. Sci. U.S.A. 89:10915-10919 for the BLOSUM 62 comparison matrix) is also used by the algorithm.

Recommended parameters for determining percent identity for polypeptides or nucleotide sequences using the GAP program are the following:

Algorithm: Needleman et al., 1970, J. Mol. Biol. 48:443-453;

Comparison matrix: BLOSUM 62 from Henikoff et al., 1992, supra;

Gap Penalty: 12 (but with no penalty for end gaps)

Gap Length Penalty: 4

Threshold of Similarity: 0

Certain alignment schemes for aligning two amino acid sequences may result in matching of only a short region of the two sequences, and this small aligned region may have very high sequence identity even though there is no significant relationship between the two full-length sequences. Accordingly, the selected alignment method (GAP program) can be adjusted if so desired to result in an alignment that spans at least 50 contiguous amino acids of the target polypeptide.

As used herein, “substantially pure” means that the described species of molecule is the predominant species present, that is, on a molar basis it is more abundant than any other individual species in the same mixture. In certain embodiments, a substantially pure molecule is a composition wherein the object species comprises at least 50% (on a molar basis) of all macromolecular species present. In other embodiments, a substantially pure composition will comprise at least 80%, 85%, 90%, 95%, or 99% of all macromolecular species present in the composition. In other embodiments, the object species is purified to essential homogeneity wherein contaminating species cannot be detected in the composition by conventional detection methods and thus the composition consists of a single detectable macromolecular species.

The term “treating” refers to any indicia of success in the treatment or amelioration of an injury, pathology or condition, including any objective or subjective parameter such as abatement; remission; diminishing of symptoms or making the injury, pathology or condition more tolerable to the patient; slowing in the rate of degeneration or decline; making the final point of degeneration less debilitating; improving a patient's physical or mental well-being. The treatment or amelioration of symptoms can be based on objective or subjective parameters; including the results of a physical examination, neuropsychiatric exams, and/or a psychiatric evaluation. For example, certain methods presented herein successfully treat migraine headaches either prophylactically or as an acute treatment, decreasing the frequency of migraine headaches, decreasing the severity of migraine headaches, and/or ameliorating a symptom associated with migraine headaches.

An “effective amount” is generally an amount sufficient to reduce the severity and/or frequency of symptoms, eliminate the symptoms and/or underlying cause, prevent the occurrence of symptoms and/or their underlying cause, and/or improve or remediate the damage that results from or is associated with migraine headache. In some embodiments, the effective amount is a therapeutically effective amount or a prophylactically effective amount. A “therapeutically effective amount” is an amount sufficient to remedy a disease state (e.g. migraine headache) or symptoms, particularly a state or symptoms associated with the disease state, or otherwise prevent, hinder, retard or reverse the progression of the disease state or any other undesirable symptom associated with the disease in any way whatsoever. A “prophylactically effective amount” is an amount of a pharmaceutical composition that, when administered to a subject, will have the intended prophylactic effect, e.g., preventing or delaying the onset (or reoccurrence) of migraine headache, or reducing the likelihood of the onset (or reoccurrence) of migraine headache or migraine headache symptoms. The full therapeutic or prophylactic effect does not necessarily occur by administration of one dose, and may occur only after administration of a series of doses. Thus, a therapeutically or prophylactically effective amount may be administered in one or more administrations.

“Amino acid” includes its normal meaning in the art. The twenty naturally-occurring amino acids and their abbreviations follow conventional usage. See, Immunology-A Synthesis, 2nd Edition, (E. S. Golub and D. R. Green, eds.), Sinauer Associates: Sunderland, Mass. (1991), incorporated herein by reference for any purpose. Stereoisomers (e.g., D-amino acids) of the twenty conventional amino acids, unnatural amino acids such as α-,α-disubstituted amino acids, N-alkyl amino acids, and other unconventional amino acids may also be suitable components for polypeptides and are included in the phrase “amino acid.” Examples of unconventional amino acids include: 4-hydroxyproline, γ-carboxyglutamate, ε-N,N,N-trimethyllysine, ε-N-acetyllysine, O-phosphoserine, N-acetylserine, N-formylmethionine, 3-methylhistidine, 5-hydroxylysine, σ-N-methylarginine, and other similar amino acids and imino acids (e.g., 4-hydroxyproline). In the polypeptide notation used herein, the left-hand direction is the amino terminal direction and the right-hand direction is the carboxyl-terminal direction, in accordance with standard usage and convention.

PAC1 in Disease

Neuropeptides present in the perivascular space of cranial vessels have been implicated as important mediators of nociceptive input during migraine attacks. Pituitary adenylate cyclase-activating polypeptide (PACAP) is present in sensory trigeminal neurons and may modulate nociception at different levels of the nervous system. Human experimental studies have shown that PACAP38 induces both headache and migraine-like attacks (Schytz, et al., 2009, “PACAP38 induces migraine-like attacks in patients with migraine without aura”, Brain: 132 pp 16-25), supporting the idea that PAC1 receptor antagonists may be used in the prophylactic and/or acute treatment of migraine.

Antibodies

Antibodies that bind PAC1 protein, including human PAC1 (hPAC1) protein are provided herein. The antibodies provided are polypeptides into which one or more complementary determining regions (CDRs), as described herein, are embedded and/or joined. In some antibodies, the CDRs are embedded into a “framework” region, which orients the CDR(s) such that the proper antigen binding properties of the CDR(s) is achieved. In general, antibodies that are provided can interfere with, block, reduce or modulate the interaction between PAC1 and its ligand(s), e.g., PACAP, such as PACAP-38.

In certain embodiments, the antibodies include, but not limited to, monoclonal antibodies, bispecific antibodies, minibodies, domain antibodies, synthetic antibodies (sometimes referred to herein as “antibody mimetics”), chimeric antibodies, humanized antibodies, human antibodies, antibody fusions (sometimes referred to herein as “antibody conjugates”), and fragments thereof. The various structures are further described herein below.

The antibodies provided herein have been demonstrated to bind to PAC1, in particular human PAC1 and cyno PAC1. As described further in the examples below, certain antibodies were tested and found to bind to epitopes different from those bound by a number of other antibodies directed against one or the other of the components of PAC1. The antibodies that are provided prevent PACAP (e.g., PACAP-38) from binding to its receptor. As a consequence, the antibodies provided herein are capable of inhibiting PAC1 activity. In particular, antibodies binding to these epitopes can have one or more of the following activities: inhibiting, inter alia, induction of PAC1 signal transduction pathways, inhibiting vasodialation, causing vasoconstriction, decreasing inflammation, e.g., neurogenic inflammation, and other physiological effects induced by PAC1 upon PACAP binding.

The antibodies that are disclosed herein have a variety of utilities. Some of the antibodies, for instance, are useful in specific binding assays, affinity purification of PAC1, in particular hPAC1 or its ligands and in screening assays to identify other antagonists of PAC1 activity. Some of the antibodies are useful for inhibiting binding of a PAC1 ligand (e.g., PACAP-38) to PAC1.

The antibodies can be used in a variety of treatment applications, as explained herein. For example, certain PAC1 antibodies are useful for treating conditions associated with PAC1 mediated signaling, such as reducing, alleviating, or treating the frequency and/or severity of migraine headache, reducing, alleviating, or treating cluster headache, reducing, alleviating, or treating chronic pain, alleviating or treating diabetes mellitus (type II), reducing, alleviating, or treating cardiovascular disorders, and reducing, alleviating, or treating hemodynamic derangements associated with endotoxemia and sepsis in a patient. Other uses for the antibodies include, for example, diagnosis of PAC1-associated diseases or conditions and screening assays to determine the presence or absence of PAC1. Some of the antibodies described herein are useful in treating consequences, symptoms, and/or the pathology associated with PAC1 activity. These include, but are not limited to, various types of headaches, including migraine (e.g., chronic and/or episodic migraine).

Some of the antibodies that are provided have the structure typically associated with naturally occurring antibodies. The structural units of these antibodies typically comprise one or more tetramers, each composed of two identical couplets of polypeptide chains, though some species of mammals also produce antibodies having only a single heavy chain. In a typical antibody, each pair or couplet includes one full-length “light” chain (in certain embodiments, about 25 kDa) and one full-length “heavy” chain (in certain embodiments, about 50-70 kDa). Each individual immunoglobulin chain is composed of several “immunoglobulin domains”, each consisting of roughly 90 to 110 amino acids and expressing a characteristic folding pattern. These domains are the basic units of which antibody polypeptides are composed. The amino-terminal portion of each chain typically includes a variable domain that is responsible for antigen recognition. The carboxy-terminal portion is more conserved evolutionarily than the other end of the chain and is referred to as the “constant region” or “C region”. Human light chains generally are classified as kappa and lambda light chains, and each of these contains one variable domain and one constant domain. Heavy chains are typically classified as mu, delta, gamma, alpha, or epsilon chains, and these define the antibody's isotype as IgM, IgD, IgG, IgA, and IgE, respectively. IgG has several subtypes, including, but not limited to, IgG1, IgG2, IgG3, and IgG4. IgM subtypes include IgM, and IgM2. IgA subtypes include IgA1 and IgA2. In humans, the IgA and IgD isotypes contain four heavy chains and four light chains; the IgG and IgE isotypes contain two heavy chains and two light chains; and the IgM isotype contains five heavy chains and five light chains. The heavy chain C region typically comprises one or more domains that may be responsible for effector function. The number of heavy chain constant region domains will depend on the isotype. IgG heavy chains, for example, each contain three C region domains known as C_(H)1, C_(H)2 and C_(H)3. The antibodies that are provided can have any of these isotypes and subtypes. In certain embodiments, the PAC1 antibody is of the IgG1, IgG2, or IgG4 subtype.

In full-length light and heavy chains, the variable and constant regions are joined by a “J” region of about twelve or more amino acids, with the heavy chain also including a “D” region of about ten more amino acids. See, e.g., Fundamental Immunology, 2nd ed., Ch. 7 (Paul, W., ed.) 1989, New York: Raven Press (hereby incorporated by reference in its entirety for all purposes). The variable regions of each light/heavy chain pair typically form the antigen binding site.

Variable regions of immunoglobulin chains generally exhibit the same overall structure, comprising relatively conserved framework regions (FR) joined by three hypervariable regions, more often called “complementarity determining regions” or CDRs. The CDRs from the two chains of each heavy chain/light chain pair mentioned above typically are aligned by the framework regions to form a structure that binds specifically with a specific epitope on the target protein (e.g., PAC1). From N-terminal to C-terminal, naturally-occurring light and heavy chain variable regions both typically conform with the following order of these elements: FR1, CDR1, FR2, CDR2, FR3, CDR3 and FR4. A numbering system has been devised for assigning numbers to amino acids that occupy positions in each of these domains. This numbering system is defined in Kabat Sequences of Proteins of Immunological Interest (1987 and 1991, NIH, Bethesda, Md.), or Chothia & Lesk, 1987, J. Mol. Biol. 196:901-917; Chothia et al., 1989, Nature 342:878-883.

The various heavy chain and light chain variable regions provided herein are depicted in Tables 3A and 3B. Each of these variable regions may be attached to the above heavy and light chain constant regions to form a complete antibody heavy and light chain, respectively. Further, each of the so generated heavy and light chain sequences may be combined to form a complete antibody structure. It should be understood that the heavy chain and light chain variable regions provided herein can also be attached to other constant domains having different sequences than the exemplary sequences listed above.

Nucleic acids that encode for the antibodies described herein, or portions thereof, are also provided, including nucleic acids encoding one or both chains of an antibody, or a fragment, derivative, mutein, or variant thereof, polynucleotides encoding heavy chain variable regions or only CDRs, polynucleotides sufficient for use as hybridization probes, PCR primers or sequencing primers for identifying, analyzing, mutating or amplifying a polynucleotide encoding a polypeptide, anti-sense nucleic acids for inhibiting expression of a polynucleotide, and complementary sequences of the foregoing. The nucleic acids can be any length. They can be, for example, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 75, 100, 125, 150, 175, 200, 250, 300, 350, 400, 450, 500, 750, 1,000, 1,500 or more nucleotides in length, and/or can comprise one or more additional sequences, for example, regulatory sequences, and/or be part of a larger nucleic acid, for example, a vector. The nucleic acids can be single-stranded or double-stranded and can comprise RNA and/or DNA nucleotides, and artificial variants thereof (e.g., peptide nucleic acids).

Tables 1A and 1B show exemplary nucleic acid sequences. Any variable region provided herein may be attached to these constant regions to form complete heavy and light chain sequences. However, it should be understood that these constant regions sequences are provided as specific examples only—one of skill in the art may employ other constant regions, including IgG1 heavy chain constant region, IgG3 or IgG4 heavy chain constant regions, any of the seven lambda light chain constant regions, including hCL-1, hCL-2, hCL-3 and hCL-7; constant regions that have been modified for improved stability, expression, manufacturability or other desired characteristics, and the like. In some embodiments, the variable region sequences are joined to other constant region sequences that are known in the art.

Specific examples of full length light and heavy chains of the antibodies that are provided and their corresponding nucleic and amino acid sequences are summarized in Tables 1A, 1B, 2A and 2B. Tables 1A and 2A show exemplary light chain sequences, and Tables 1B and 2B show exemplary heavy chain sequences, which are shown without the respective signal sequences.

Also provided are antibodies (and corresponding nucleic acid sequences) that contain an antibody light chain variable region or an antibody heavy chain variable region, as shown in Tables 3A and 3B below, and immunologically functional fragments, derivatives, muteins and variants of these light chain and heavy chain variable regions.

Also included are nucleic acid sequences encoding the variable regions shown in Tables 3A and 3B. Because those sequences are contained in the full-length nucleic acid sequences of the corresponding antibodies shown in Tables 1A and 1B, they are not culled out as separate sequences in a table or in the Sequence Listing, but can be readily ascertained by one of skill in the art based on the variable regions provided in Tables 3A and 3B, together with the full length DNA sequences in Tables 1A and 1B.

Antibodies of this type can generally be designated by the formula “V_(H)x/V_(L)y,” where “x” corresponds to the number of heavy chain variable regions and “y” corresponds to the number of the light chain variable regions.

CDRs

The antibodies disclosed herein are polypeptides into which one or more CDRs are grafted, inserted and/or joined. An antibody can have 1, 2, 3, 4, 5 or 6 CDRs. An antibody thus can have, for example, one heavy chain CDR1 (“CDRH1”), and/or one heavy chain CDR2 (“CDRH2”), and/or one heavy chain CDR3 (“CDRH3”), and/or one light chain CDR1 (“CDRL1”), and/or one light chain CDR2 (“CDRL2”), and/or one light chain CDR3 (“CDRL3”). Some antibodies include both a CDRH3 and a CDRL3. Specific heavy and light chain CDRs are identified in Tables 3A and 3B, respectively.

Complementarity determining regions (CDRs) and framework regions (FR) of a given antibody may be identified using the system described by Kabat et al. in Sequences of Proteins of Immunological Interest, 5th Ed., US Dept. of Health and Human Services, PHS, NIH, NIH Publication no. 91-3242, 1991.

The structure and properties of CDRs within a naturally occurring antibody has been described, supra. Briefly, in a traditional antibody, the CDRs are embedded within a framework in the heavy and light chain variable region where they constitute the regions responsible for antigen binding and recognition. A variable region comprises at least three heavy or light chain CDRs, see, supra (Kabat et al., 1991, Sequences of Proteins of Immunological Interest, Public Health Service N.I.H., Bethesda, Md.; see also Chothia and Lesk, 1987, J. Mol. Biol. 196:901-917; Chothia et al., 1989, Nature 342: 877-883), within a framework region (designated framework regions 1-4, FR1, FR2, FR3, and FR4, by Kabat et al., 1991, supra; see also Chothia and Lesk, 1987, supra). The CDRs provided herein, however, may not only be used to define the antigen binding domain of a traditional antibody structure, but may be embedded in a variety of other polypeptide structures, as described herein.

Some of the antibodies disclosed herein share certain regions or sequences with other antibodies disclosed herein. These relationships are summarized in the tables above.

In one aspect, the isolated antibodies provided herein can be a monoclonal antibody, a polyclonal antibody, a recombinant antibody, a human antibody, a humanized antibody, a chimeric antibody, a multispecific antibody, or an antibody antigen binding fragment thereof.

In another embodiment, the antibody fragment of the isolated antibodies provided herein can be a Fab fragment, a Fab′ fragment, an F(ab′)₂ fragment, an Fv fragment, a diabody, or a single chain antibody molecule.

In a further embodiment, the isolated antibody provided herein is a human antibody and can be of the IgG1-, IgG2-IgG3- or IgG4-type. In a further embodiment, the isolated antibody is an IgG1- or IgG2-type. In a further embodiment, the isolated antibody is an IgG2-type. In a further embodiment, the isolated antibody is an IgG1-type. In a further embodiment, the IgG1-type antibody is an aglycosylated IgG1 antibody. In a further embodiment, the aglycosylated IgG1 antibody has an N297G mutation.

In another embodiment, the antibody consists of a just a light or a heavy chain polypeptide as set forth in Tables 2A-2B. In some embodiments, the antibody consists just of a light chain variable or heavy chain variable domain such as those listed in Tables 3A and 3B. Such antibodies can be pegylated with one or more PEG molecules.

In yet another aspect, the isolated antibody provided herein can be coupled to a labeling group and can compete for binding to the extracellular portion of human PAC1 with an antibody of one of the isolated antibodies provided herein. In one embodiment, the isolated antibody provided herein can reduce monocyte chemotaxis, inhibit monocyte migration into tumors or inhibit accumulation and function of tumor associated macrophage in a tumor when administered to a patient.

As will be appreciated by those in the art, for any antibody with more than one CDR from the depicted sequences, any combination of CDRs independently selected from the depicted sequences is useful. Thus, antibodies with one, two, three, four, five or six of independently selected CDRs can be generated. However, as will be appreciated by those in the art, specific embodiments generally utilize combinations of CDRs that are non-repetitive, e.g., antibodies are generally not made with two CDRH2 regions, etc.

Monoclonal Antibodies

The antibodies that are provided include monoclonal antibodies that bind to PAC1. Monoclonal antibodies may be produced using any technique known in the art, e.g., by immortalizing spleen cells harvested from the transgenic animal after completion of the immunization schedule. The spleen cells can be immortalized using any technique known in the art, e.g., by fusing them with myeloma cells to produce hybridomas. Myeloma cells for use in hybridoma-producing fusion procedures preferably are non-antibody-producing, have high fusion efficiency, and enzyme deficiencies that render them incapable of growing in certain selective media which support the growth of only the desired fused cells (hybridomas). Examples of suitable cell lines for use in mouse fusions include Sp-20, P3-X63/Ag8, P3-X63-Ag8.653, NS1/1.Ag 4 l, Sp210-Ag14, FO, NSO/U, MPC-11, MPC11-X45-GTG 1.7 and S194/5XXO Bul; examples of cell lines used in rat fusions include R210.RCY3, Y3-Ag 1.2.3, IR983F and 4B210. Other cell lines useful for cell fusions are U-266, GM1500-GRG2, LICR-LON-HMy2 and UC729-6.

In some instances, a hybridoma cell line is produced by immunizing an animal (e.g., a transgenic animal having human immunoglobulin sequences) with a PAC1 immunogen; harvesting spleen cells from the immunized animal; fusing the harvested spleen cells to a myeloma cell line, thereby generating hybridoma cells; establishing hybridoma cell lines from the hybridoma cells, and identifying a hybridoma cell line that produces an antibody that binds PAC1 (e.g., as described in Examples 1-3, below). Such hybridoma cell lines, and anti-PAC1 monoclonal antibodies produced by them, are aspects of the present application.

Monoclonal antibodies secreted by a hybridoma cell line can be purified using any technique known in the art.

Chimeric and Humanized Antibodies

Chimeric and humanized antibodies based upon the foregoing sequences are also provided. Monoclonal antibodies for use as therapeutic agents may be modified in various ways prior to use. One example is a chimeric antibody, which is an antibody composed of protein segments from different antibodies that are covalently joined to produce functional immunoglobulin light or heavy chains or immunologically functional portions thereof. Generally, a portion of the heavy chain and/or light chain is identical with or homologous to a corresponding sequence in antibodies derived from a particular species or belonging to a particular antibody class or subclass, while the remainder of the chain(s) is/are identical with or homologous to a corresponding sequence in antibodies derived from another species or belonging to another antibody class or subclass. For methods relating to chimeric antibodies, see, for example, U.S. Pat. No. 4,816,567; and Morrison et al., 1985, Proc. Natl. Acad. Sci. USA 81:6851-6855, which are hereby incorporated by reference. CDR grafting is described, for example, in U.S. Pat. Nos. 6,180,370, 5,693,762, 5,693,761, 5,585,089, and 5,530,101.

Generally, the goal of making a chimeric antibody is to create a chimera in which the number of amino acids from the intended patient species is maximized. One example is the “CDR-grafted” antibody, in which the antibody comprises one or more complementarity determining regions (CDRs) from a particular species or belonging to a particular antibody class or subclass, while the remainder of the antibody chain(s) is/are identical with or homologous to a corresponding sequence in antibodies derived from another species or belonging to another antibody class or subclass. For use in humans, the variable region or selected CDRs from a rodent antibody often are grafted into a human antibody, replacing the naturally-occurring variable regions or CDRs of the human antibody.

One useful type of chimeric antibody is a “humanized” antibody. Generally, a humanized antibody is produced from a monoclonal antibody raised initially in a non-human animal. Certain amino acid residues in this monoclonal antibody, typically from non-antigen recognizing portions of the antibody, are modified to be homologous to corresponding residues in a human antibody of corresponding isotype. Humanization can be performed, for example, using various methods by substituting at least a portion of a rodent variable region for the corresponding regions of a human antibody (see, e.g., U.S. Pat. Nos. 5,585,089, and 5,693,762; Jones et al., 1986, Nature 321:522-525; Riechmann et al., 1988, Nature 332:323-27; Verhoeyen et al., 1988, Science 239:1534-1536),

In one aspect, the CDRs of the light and heavy chain variable regions of the antibodies provided herein are grafted to framework regions (FRs) from antibodies from the same, or a different, phylogenetic species. For example, the CDRs of the heavy and light chain variable regions described herein can be grafted to consensus human FRs. To create consensus human FRs, FRs from several human heavy chain or light chain amino acid sequences may be aligned to identify a consensus amino acid sequence. In other embodiments, the FRs of a heavy chain or light chain disclosed herein are replaced with the FRs from a different heavy chain or light chain. In one aspect, rare amino acids in the FRs of the heavy and light chains of anti-PAC1 antibody are not replaced, while the rest of the FR amino acids are replaced. A “rare amino acid” is a specific amino acid that is in a position in which this particular amino acid is not usually found in an FR. Alternatively, the grafted variable regions from the one heavy or light chain may be used with a constant region that is different from the constant region of that particular heavy or light chain as disclosed herein. In other embodiments, the grafted variable regions are part of a single chain Fv antibody.

In certain embodiments, constant regions from species other than human can be used along with the human variable region(s) to produce hybrid antibodies.

Fully Human Antibodies

Fully human antibodies are also provided. Methods are available for making fully human antibodies specific for a given antigen without exposing human beings to the antigen (“fully human antibodies”). One specific means provided for implementing the production of fully human antibodies is the “humanization” of the mouse humoral immune system. Introduction of human immunoglobulin (Ig) loci into mice in which the endogenous Ig genes have been inactivated is one means of producing fully human monoclonal antibodies (mAbs) in mouse, an animal that can be immunized with any desirable antigen. Using fully human antibodies can minimize the immunogenic and allergic responses that can sometimes be caused by administering mouse or mouse-derived mAbs to humans as therapeutic agents.

Fully human antibodies can be produced by immunizing transgenic animals (usually mice) that are capable of producing a repertoire of human antibodies in the absence of endogenous immunoglobulin production. Antigens for this purpose typically have six or more contiguous amino acids, and optionally are conjugated to a carrier, such as a hapten. See, e.g., Jakobovits et al., 1993, Proc. Natl. Acad. Sci. USA 90:2551-2555; Jakobovits et al., 1993, Nature 362:255-258; and Bruggermann et al., 1993, Year in Immunol. 7:33. In one example of such a method, transgenic animals are produced by incapacitating the endogenous mouse immunoglobulin loci encoding the mouse heavy and light immunoglobulin chains therein, and inserting into the mouse genome large fragments of human genome DNA containing loci that encode human heavy and light chain proteins. Partially modified animals, which have less than the full complement of human immunoglobulin loci, are then cross-bred to obtain an animal having all of the desired immune system modifications. When administered an immunogen, these transgenic animals produce antibodies that are immunospecific for the immunogen but have human rather than murine amino acid sequences, including the variable regions. For further details of such methods, see, for example, WO96/33735 and WO94/02602. Additional methods relating to transgenic mice for making human antibodies are described in U.S. Pat. Nos. 5,545,807; 6,713,610; 6,673,986; 6,162,963; 5,545,807; 6,300,129; 6,255,458; 5,877,397; 5,874,299 and 5,545,806; in PCT publications WO91/10741, WO90/04036, and in EP 546073B1 and EP 546073A1.

The transgenic mice described above, referred to herein as “HuMab” mice, contain a human immunoglobulin gene minilocus that encodes unrearranged human heavy ([mu] and [gamma]) and [kappa] light chain immunoglobulin sequences, together with targeted mutations that inactivate the endogenous [mu] and [kappa] chain loci (Lonberg et al., 1994, Nature 368:856-859). Accordingly, the mice exhibit reduced expression of mouse IgM or [kappa] and in response to immunization, and the introduced human heavy and light chain transgenes undergo class switching and somatic mutation to generate high affinity human IgG [kappa] monoclonal antibodies (Lonberg et al., supra.; Lonberg and Huszar, 1995, Intern. Rev. Immunol. 13: 65-93; Harding and Lonberg, 1995, Ann. N.Y. Acad. Sci. 764:536-546). The preparation of HuMab mice is described in detail in Taylor et al., 1992, Nucleic Acids Research 20:6287-6295; Chen et al., 1993, International Immunology 5:647-656; Tuaillon et al., 1994, J. Immunol. 152:2912-2920; Lonberg et al., 1994, Nature 368:856-859; Lonberg, 1994, Handbook of Exp. Pharmacology 113:49-101; Taylor et al., 1994, International Immunology 6:579-591; Lonberg and Huszar, 1995, Intern. Rev. Immunol. 13:65-93; Harding and Lonberg, 1995, Ann. N.Y. Acad. Sci. 764:536-546; Fishwild et al., 1996, Nature Biotechnology 14:845-851; the foregoing references are hereby incorporated by reference in their entirety for all purposes. See, further U.S. Pat. Nos. 5,545,806; 5,569,825; 5,625,126; 5,633,425; 5,789,650; 5,877,397; 5,661,016; 5,814,318; 5,874,299; and 5,770,429; as well as U.S. Pat. No. 5,545,807; International Publication Nos. WO 93/1227; WO 92/22646; and WO 92/03918, the disclosures of all of which are hereby incorporated by reference in their entirety for all purposes. Technologies utilized for producing human antibodies in these transgenic mice are disclosed also in WO 98/24893, and Mendez et al., 1997, Nature Genetics 15:146-156, which are hereby incorporated by reference. For example, the HCo7 and HCo12 transgenic mice strains can be used to generate anti-PAC1 antibodies. Further details regarding the production of human antibodies using transgenic mice are provided in the examples below.

Using hybridoma technology, antigen-specific human mAbs with the desired specificity can be produced and selected from the transgenic mice such as those described above. Such antibodies may be cloned and expressed using a suitable vector and host cell, or the antibodies can be harvested from cultured hybridoma cells.

Fully human antibodies can also be derived from phage-display libraries (as disclosed in Hoogenboom et al., 1991, J. Mol. Biol. 227:381; and Marks et al., 1991, J. Mol. Biol. 222:581). Phage display techniques mimic immune selection through the display of antibody repertoires on the surface of filamentous bacteriophage, and subsequent selection of phage by their binding to an antigen of choice. One such technique is described in PCT Publication No. WO 99/10494 (hereby incorporated by reference), which describes the isolation of high affinity and functional agonistic antibodies for MPL- and msk-receptors using such an approach.

Bispecific Or Bifunctional Antibodies

The antibodies that are provided also include bispecific and bifunctional antibodies that include one or more CDRs or one or more variable regions as described above. A bispecific or bifunctional antibody in some instances is an artificial hybrid antibody having two different heavy/light chain pairs and two different binding sites. Bispecific antibodies may be produced by a variety of methods including, but not limited to, fusion of hybridomas or linking of Fab′ fragments. See, e.g., Songsivilai and Lachmann, 1990, Clin. Exp. Immunol. 79:315-321; Kostelny et al., 1992, J. Immunol. 148:1547-1553.

Various Other Forms

Some of the antibodies that are provided are variant forms of the antibodies disclosed above. For instance, some of the antibodies have one or more conservative amino acid substitutions in one or more of the heavy or light chains, variable regions or CDRs listed above.

Naturally-occurring amino acids may be divided into classes based on common side chain properties:

1) hydrophobic: norleucine, Met, Ala, Val, Leu, Ile;

2) neutral hydrophilic: Cys, Ser, Thr, Asn, Gln;

3) acidic: Asp, Glu;

4) basic: His, Lys, Arg;

5) residues that influence chain orientation: Gly, Pro; and

6) aromatic: Trp, Tyr, Phe.

Conservative amino acid substitutions may involve exchange of a member of one of these classes with another member of the same class. Conservative amino acid substitutions may encompass non-naturally occurring amino acid residues, which are typically incorporated by chemical peptide synthesis rather than by synthesis in biological systems. These include peptidomimetics and other reversed or inverted forms of amino acid moieties.

Non-conservative substitutions may involve the exchange of a member of one of the above classes for a member from another class. Such substituted residues may be introduced into regions of the antibody that are homologous with human antibodies, or into the non-homologous regions of the molecule.

In making such changes, according to certain embodiments, the hydropathic index of amino acids may be considered. The hydropathic profile of a protein is calculated by assigning each amino acid a numerical value (“hydropathy index”) and then repetitively averaging these values along the peptide chain. Each amino acid has been assigned a hydropathic index on the basis of its hydrophobicity and charge characteristics. They are: isoleucine (+4.5); valine (+4.2); leucine (+3.8); phenylalanine (+2.8); cysteine/cystine (+2.5); methionine (+1.9); alanine (+1.8); glycine (−0.4); threonine (−0.7); serine (−0.8); tryptophan (−0.9); tyrosine (−1.3); proline (−1.6); histidine (−3.2); glutamate (−3.5); glutamine (−3.5); aspartate (−3.5); asparagine (−3.5); lysine (−3.9); and arginine (−4.5).

The importance of the hydropathic profile in conferring interactive biological function on a protein is understood in the art (see, e.g., Kyte et al., 1982, J. Mol. Biol. 157:105-131). It is known that certain amino acids may be substituted for other amino acids having a similar hydropathic index or score and still retain a similar biological activity. In making changes based upon the hydropathic index, in certain embodiments, the substitution of amino acids whose hydropathic indices are within ±2 is included. In some aspects, those which are within ±1 are included, and in other aspects, those within ±0.5 are included.

It is also understood in the art that the substitution of like amino acids can be made effectively on the basis of hydrophilicity, particularly where the biologically functional protein or peptide thereby created is intended for use in immunological embodiments, as in the present case. In certain embodiments, the greatest local average hydrophilicity of a protein, as governed by the hydrophilicity of its adjacent amino acids, correlates with its immunogenicity and antigen-bindingor immunogenicity, that is, with a biological property of the protein.

The following hydrophilicity values have been assigned to these amino acid residues: arginine (+3.0); lysine (+3.0); aspartate (+3.0±1); glutamate (+3.0±1); serine (+0.3); asparagine (+0.2); glutamine (+0.2); glycine (0); threonine (−0.4); proline (−0.5±1); alanine (−0.5); histidine (−0.5); cysteine (−1.0); methionine (−1.3); valine (−1.5); leucine (−1.8); isoleucine (−1.8); tyrosine (−2.3); phenylalanine (−2.5) and tryptophan (−3.4). In making changes based upon similar hydrophilicity values, in certain embodiments, the substitution of amino acids whose hydrophilicity values are within ±2 is included, in other embodiments, those which are within ±1 are included, and in still other embodiments, those within ±0.5 are included. In some instances, one may also identify epitopes from primary amino acid sequences on the basis of hydrophilicity. These regions are also referred to as “epitopic core regions.”

Exemplary conservative amino acid substitutions are set forth in Table 6.

A skilled artisan will be able to determine suitable variants of polypeptides as set forth herein using well-known techniques. One skilled in the art may identify suitable areas of the molecule that may be changed without destroying activity by targeting regions not believed to be important for activity. The skilled artisan also will be able to identify residues and portions of the molecules that are conserved among similar polypeptides. In further embodiments, even areas that may be important for biological activity or for structure may be subject to conservative amino acid substitutions without destroying the biological activity or without adversely affecting the polypeptide structure.

Additionally, one skilled in the art can review structure-function studies identifying residues in similar polypeptides that are important for activity or structure. In view of such a comparison, one can predict the importance of amino acid residues in a protein that correspond to amino acid residues important for activity or structure in similar proteins. One skilled in the art may opt for chemically similar amino acid substitutions for such predicted important amino acid residues.

One skilled in the art can also analyze the 3-dimensional structure and amino acid sequence in relation to that structure in similar polypeptides. In view of such information, one skilled in the art may predict the alignment of amino acid residues of an antibody with respect to its three dimensional structure. One skilled in the art may choose not to make radical changes to amino acid residues predicted to be on the surface of the protein, since such residues may be involved in important interactions with other molecules. Moreover, one skilled in the art may generate test variants containing a single amino acid substitution at each desired amino acid residue. These variants can then be screened using assays for PAC1 neutralizing activity, (see examples below) thus yielding information regarding which amino acids can be changed and which must not be changed. In other words, based on information gathered from such routine experiments, one skilled in the art can readily determine the amino acid positions where further substitutions should be avoided either alone or in combination with other mutations.

A number of scientific publications have been devoted to the prediction of secondary structure. See, Moult, 1996, Curr. Op. in Biotech. 7:422-427; Chou et al., 1974, Biochem. 13:222-245; Chou et al., 1974, Biochemistry 113:211-222; Chou et al., 1978, Adv. Enzymol. Relat. Areas Mol. Biol. 47:45-148; Chou et al., 1979, Ann. Rev. Biochem. 47:251-276; and Chou et al., 1979, Biophys. J. 26:367-384. Moreover, computer programs are currently available to assist with predicting secondary structure. One method of predicting secondary structure is based upon homology modeling. For example, two polypeptides or proteins that have a sequence identity of greater than 30%, or similarity greater than 40% can have similar structural topologies. The recent growth of the protein structural database (PDB) has provided enhanced predictability of secondary structure, including the potential number of folds within a polypeptide's or protein's structure. See, Holm et al., 1999, Nucl. Acid. Res. 27:244-247. It has been suggested (Brenner et al., 1997, Curr. Op. Struct. Biol. 7:369-376) that there are a limited number of folds in a given polypeptide or protein and that once a critical number of structures have been resolved, structural prediction will become dramatically more accurate.

Additional methods of predicting secondary structure include “threading” (Jones, 1997, Curr. Opin. Struct. Biol. 7:377-387; Sippl et al., 1996, Structure 4:15-19), “profile analysis” (Bowie et al., 1991, Science 253:164-170; Gribskov et al., 1990, Meth. Enzym. 183:146-159; Gribskov et al., 1987, Proc. Nat. Acad. Sci. 84:4355-4358), and “evolutionary linkage” (See, Holm, 1999, supra; and Brenner, 1997, supra).

In some embodiments, amino acid substitutions are made that: (1) reduce susceptibility to proteolysis, (2) reduce susceptibility to oxidation, (3) alter binding affinity for forming protein complexes, (4) alter ligand or antigen binding affinities, and/or (4) confer or modify other physicochemical or functional properties on such polypeptides. For example, single or multiple amino acid substitutions (in certain embodiments, conservative amino acid substitutions) may be made in the naturally-occurring sequence. Substitutions can be made in that portion of the antibody that lies outside the domain(s) forming intermolecular contacts). In such embodiments, conservative amino acid substitutions can be used that do not substantially change the structural characteristics of the parent sequence (e.g., one or more replacement amino acids that do not disrupt the secondary structure that characterizes the parent or native antibody). Examples of art-recognized polypeptide secondary and tertiary structures are described in Proteins, Structures and Molecular Principles (Creighton, Ed.), 1984, W. H. New York: Freeman and Company; Introduction to Protein Structure (Branden and Tooze, eds.), 1991, New York: Garland Publishing; and Thornton et al., 1991, Nature 354:105, which are each incorporated herein by reference.

Additional preferred antibody variants include cysteine variants wherein one or more cysteine residues in the parent or native amino acid sequence are deleted from or substituted with another amino acid (e.g., serine). Cysteine variants are useful, inter alia when antibodies must be refolded into a biologically active conformation. Cysteine variants may have fewer cysteine residues than the native antibody, and typically have an even number to minimize interactions resulting from unpaired cysteines.

The heavy and light chains, variable regions domains and CDRs that are disclosed can be used to prepare polypeptides that contain an antigen binding region that can specifically bind to PAC1. For example, one or more of the CDRs listed in Tables 4A and 4B can be incorporated into a molecule (e.g., a polypeptide) covalently or noncovalently to make an immunoadhesion. An immunoadhesion may incorporate the CDR(s) as part of a larger polypeptide chain, may covalently link the CDR(s) to another polypeptide chain, or may incorporate the CDR(s) noncovalently. The CDR(s) enable the immunoadhesion to bind specifically to a particular antigen of interest (e.g., PAC1 or epitope thereof).

Mimetics (e.g., “peptide mimetics” or “peptidomimetics”) based upon the variable region domains and CDRs that are described herein are also provided. These analogs can be peptides, non-peptides or combinations of peptide and non-peptide regions. Fauchere, 1986, Adv. Drug Res. 15:29; Veber and Freidinger, 1985, TINS p. 392; and Evans et al., 1987, J. Med. Chem. 30:1229, which are incorporated herein by reference for any purpose. Peptide mimetics that are structurally similar to therapeutically useful peptides may be used to produce a similar therapeutic or prophylactic effect. Such compounds are often developed with the aid of computerized molecular modeling. Generally, peptidomimetics are proteins that are structurally similar to an antibody displaying a desired biological activity, such as here the ability to specifically bind PAC1, but have one or more peptide linkages optionally replaced by a linkage selected from: —CH₂NH—, —CH₂S—, —CH₂—CH₂—, —CH—CH-(cis and trans), —COCH₂—, —CH(OH)CH₂—, and —CH₂SO—, by methods well known in the art. Systematic substitution of one or more amino acids of a consensus sequence with a D-amino acid of the same type (e.g., D-lysine in place of L-lysine) may be used in certain embodiments to generate more stable proteins. In addition, constrained peptides comprising a consensus sequence or a substantially identical consensus sequence variation may be generated by methods known in the art (Rizo and Gierasch, 1992, Ann. Rev. Biochem. 61:387), incorporated herein by reference), for example, by adding internal cysteine residues capable of forming intramolecular disulfide bridges which cyclize the peptide.

Derivatives of the antibodies that are described herein are also provided. The derivatized antibodies can comprise any molecule or substance that imparts a desired property to the antibody or fragment, such as increased half-life in a particular use. The derivatized antibody can comprise, for example, a detectable (or labeling) moiety (e.g., a radioactive, colorimetric, antigenic or enzymatic molecule, a detectable bead (such as a magnetic or electrodense (e.g., gold) bead), or a molecule that binds to another molecule (e.g., biotin or streptavidin)), a therapeutic or diagnostic moiety (e.g., a radioactive, cytotoxic, or pharmaceutically active moiety), or a molecule that increases the suitability of the antibody for a particular use (e.g., administration to a subject, such as a human subject, or other in vivo or in vitro uses). Examples of molecules that can be used to derivatize an antibody include albumin (e g., human serum albumin) and polyethylene glycol (PEG). Albumin-linked and PEGylated derivatives of antibodies can be prepared using techniques well known in the art. Certain antibodies include a pegylated single chain polypeptide as described herein. In one embodiment, the antibody is conjugated or otherwise linked to transthyretin (TTR) or a TTR variant. The TTR or TTR variant can be chemically modified with, for example, a chemical selected from the group consisting of dextran, poly(n-vinyl pyrrolidone), polyethylene glycols, propropylene glycol homopolymers, polypropylene oxide/ethylene oxide co-polymers, polyoxyethylated polyols and polyvinyl alcohols.

Other derivatives include covalent or aggregative conjugates of PAC1 binding proteins with other proteins or polypeptides, such as by expression of recombinant fusion proteins comprising heterologous polypeptides fused to the N-terminus or C-terminus of a PAC1 binding protein. For example, the conjugated peptide may be a heterologous signal (or leader) polypeptide, e.g., the yeast alpha-factor leader, or a peptide such as an epitope tag. PAC1 antibody-containing fusion proteins can comprise peptides added to facilitate purification or identification of the PAC1 binding protein (e.g., poly-His). A PAC1 binding protein also can be linked to the FLAG peptide as described in Hopp et al., 1988, Bio/Technology 6:1204; and U.S. Pat. No. 5,011,912. The FLAG peptide is highly antigenic and provides an epitope reversibly bound by a specific monoclonal antibody (mAb), enabling rapid assay and facile purification of expressed recombinant protein. Reagents useful for preparing fusion proteins in which the FLAG peptide is fused to a given polypeptide are commercially available (Sigma, St. Louis, Mo.).

Oligomers that contain one or more PAC1 binding proteins may be employed as PAC1 antagonists. Oligomers may be in the form of covalently-linked or non-covalently-linked dimers, trimers, or higher oligomers. Oligomers comprising two or more PAC1 binding proteins are contemplated for use, with one example being a homodimer. Other oligomers include heterodimers, homotrimers, heterotrimers, homotetramers, heterotetramers, etc.

One embodiment is directed to oligomers comprising multiple PAC1-binding polypeptides joined via covalent or non-covalent interactions between peptide moieties fused to the PAC1 binding proteins. Such peptides may be peptide linkers (spacers), or peptides that have the property of promoting oligomerization. Leucine zippers and certain polypeptides derived from antibodies are among the peptides that can promote oligomerization of PAC1 binding proteins attached thereto, as described in more detail below.

In particular embodiments, the oligomers comprise from two to four PAC1 binding proteins. The PAC1 binding protein moieties of the oligomer may be in any of the forms described above, e.g., variants or fragments. Preferably, the oligomers comprise PAC1 binding proteins that have PAC1 binding activity.

In one embodiment, an oligomer is prepared using polypeptides derived from immunoglobulins. Preparation of fusion proteins comprising certain heterologous polypeptides fused to various portions of antibody-derived polypeptides (including the Fc domain) has been described, e.g., by Ashkenazi et al., 1991, Proc. Natl. Acad. Sci. USA 88:10535; Byrn et al., 1990, Nature 344:677; and Hollenbaugh et al., 1992 “Construction of Immunoglobulin Fusion Proteins”, in Current Protocols in Immunology, Suppl. 4, pages 10.19.1-10.19.11.

One embodiment is directed to a dimer comprising two fusion proteins created by fusing a PAC1 binding protein to the Fc region of an antibody. The dimer can be made by, for example, inserting a gene fusion encoding the fusion protein into an appropriate expression vector, expressing the gene fusion in host cells transformed with the recombinant expression vector, and allowing the expressed fusion protein to assemble much like antibody molecules, whereupon interchain disulfide bonds form between the Fc moieties to yield the dimer.

The term “Fc polypeptide” as used herein includes native and mutein forms of polypeptides derived from the Fc region of an antibody. Truncated forms of such polypeptides containing the hinge region that promotes dimerization also are included. Fusion proteins comprising Fc moieties (and oligomers formed therefrom) offer the advantage of facile purification by affinity chromatography over Protein A or Protein G columns.

One suitable Fc polypeptide, described in PCT application WO 93/10151 and U.S. Pat. Nos. 5,426,048 and 5,262,522, is a single chain polypeptide extending from the N-terminal hinge region to the native C-terminus of the Fc region of a human IgG1 antibody. Another useful Fc polypeptide is the Fc mutein described in U.S. Pat. No. 5,457,035, and in Baum et al., 1994, EMBO J. 13:3992-4001. The amino acid sequence of this mutein is identical to that of the native Fc sequence presented in WO 93/10151, except that amino acid 19 has been changed from Leu to Ala, amino acid 20 has been changed from Leu to Glu, and amino acid 22 has been changed from Gly to Ala. The mutein exhibits reduced affinity for Fc receptors.

In other embodiments, the variable portion of the heavy and/or light chains of a PAC1 binding protein such as disclosed herein may be substituted for the variable portion of an antibody heavy and/or light chain.

Alternatively, the oligomer is a fusion protein comprising multiple PAC1 binding proteins, with or without peptide linkers (spacer peptides). Among the suitable peptide linkers are those described in U.S. Pat. Nos. 4,751,180 and 4,935,233.

Another method for preparing oligomeric PAC1 binding protein derivatives involves use of a leucine zipper. Leucine zipper domains are peptides that promote oligomerization of the proteins in which they are found. Leucine zippers were originally identified in several DNA-binding proteins (Landschulz et al., 1988, Science 240:1759), and have since been found in a variety of different proteins. Among the known leucine zippers are naturally occurring peptides and derivatives thereof that dimerize or trimerize. Examples of leucine zipper domains suitable for producing soluble oligomeric proteins are described in PCT application WO 94/10308, and the leucine zipper derived from lung surfactant protein D (SPD) described in Hoppe et al., 1994, FEBS Letters 344:191, hereby incorporated by reference. The use of a modified leucine zipper that allows for stable trimerization of a heterologous protein fused thereto is described in Fanslow et al., 1994, Semin. Immunol. 6:267-278. In one approach, recombinant fusion proteins comprising a PAC1 binding protein fragment or derivative fused to a leucine zipper peptide are expressed in suitable host cells, and the soluble oligomeric PAC1 binding protein fragments or derivatives that form are recovered from the culture supernatant.

In certain embodiments, the antibody has a K_(D) (equilibrium binding affinity) of less than 1 pM, 10 pM, 100 pM, 1 nM, 2 nM, 5 nM, 10 nM, 25 nM or 50 nM.

Another aspect provides an antibody having a half-life of at least one day in vitro or in vivo (e.g., when administered to a human subject). In one embodiment, the antibody has a half-life of at least three days. In another embodiment, the antibody or portion thereof has a half-life of four days or longer. In another embodiment, the antibody or portion thereof has a half-life of eight days or longer. In another embodiment, the antibody or antigen-binding portion thereof is derivatized or modified such that it has a longer half-life as compared to the underivatized or unmodified antibody. In another embodiment, the antibody contains point mutations to increase serum half life, such as described in WO 00/09560, published Feb. 24, 2000, incorporated by reference.

Glycosylation

The antibody may have a glycosylation pattern that is different or altered from that found in the native species. As is known in the art, glycosylation patterns can depend on both the sequence of the protein (e.g., the presence or absence of particular glycosylation amino acid residues, discussed below), or the host cell or organism in which the protein is produced. Particular expression systems are discussed below.

Glycosylation of polypeptides is typically either N-linked or O-linked. N-linked refers to the attachment of the carbohydrate moiety to the side chain of an asparagine residue. The tri-peptide sequences asparagine-X-serine and asparagine-X-threonine, where X is any amino acid except proline, are the recognition sequences for enzymatic attachment of the carbohydrate moiety to the asparagine side chain. Thus, the presence of either of these tri-peptide sequences in a polypeptide creates a potential glycosylation site. O-linked glycosylation refers to the attachment of one of the sugars N-acetylgalactosamine, galactose, or xylose, to a hydroxyamino acid, most commonly serine or threonine, although 5-hydroxyproline or 5-hydroxylysine may also be used.

Addition of glycosylation sites to the antibody is conveniently accomplished by altering the amino acid sequence such that it contains one or more of the above-described tri-peptide sequences (for N-linked glycosylation sites). The alteration may also be made by the addition of, or substitution by, one or more serine or threonine residues to the starting sequence (for O-linked glycosylation sites). For ease, the antibody amino acid sequence may be altered through changes at the DNA level, particularly by mutating the DNA encoding the target polypeptide at preselected bases such that codons are generated that will translate into the desired amino acids.

Another means of increasing the number of carbohydrate moieties on the antibody is by chemical or enzymatic coupling of glycosides to the protein. These procedures are advantageous in that they do not require production of the protein in a host cell that has glycosylation capabilities for N- and O-linked glycosylation. Depending on the coupling mode used, the sugar(s) may be attached to (a) arginine and histidine, (b) free carboxyl groups, (c) free sulfhydryl groups such as those of cysteine, (d) free hydroxyl groups such as those of serine, threonine, or hydroxyproline, (e) aromatic residues such as those of phenylalanine, tyrosine, or tryptophan, or (f) the amide group of glutamine. These methods are described in WO 87/05330 published Sep. 11, 1987, and in Aplin and Wriston, 1981, CRC Crit. Rev, Biochem., pp. 259-306.

Removal of carbohydrate moieties present on the starting antibody may be accomplished chemically or enzymatically. Chemical deglycosylation requires exposure of the protein to the compound trifluoromethanesulfonic acid, or an equivalent compound. This treatment results in the cleavage of most or all sugars except the linking sugar (N-acetylglucosamine or N-acetylgalactosamine), while leaving the polypeptide intact. Chemical deglycosylation is described by Hakimuddin et al., 1987, Arch. Biochem. Biophys. 259:52 and by Edge et al., 1981, Anal. Biochem. 118:131. Enzymatic cleavage of carbohydrate moieties on polypeptides can be achieved by the use of a variety of endo- and exo-glycosidases as described by Thotakura et al., 1987, Meth. Enzymol. 138:350. Glycosylation at potential glycosylation sites may be prevented by the use of the compound tunicamycin as described by Duskin et al., 1982, J. Biol. Chem. 257:3105. Tunicamycin blocks the formation of protein-N-glycoside linkages.

Hence, aspects include glycosylation variants of the antibodies wherein the number and/or type of glycosylation site(s) has been altered compared to the amino acid sequences of the parent polypeptide. In certain embodiments, antibody protein variants comprise a greater or a lesser number of N-linked glycosylation sites than the native antibody. An N-linked glycosylation site is characterized by the sequence: Asn-X-Ser or Asn-X-Thr, wherein the amino acid residue designated as X may be any amino acid residue except proline. The substitution of amino acid residues to create this sequence provides a potential new site for the addition of an N-linked carbohydrate chain. Alternatively, substitutions that eliminate or alter this sequence will prevent addition of an N-linked carbohydrate chain present in the native polypeptide. For example, the glycosylation can be reduced by the deletion of an Asn or by substituting the Asn with a different amino acid. In other embodiments, one or more new N-linked sites are created. Antibodies typically have a N-linked glycosylation site in the Fc region.

It is known that human IgG1 has a glycosylation site at N297 (EU numbering system) and glycosylation contributes to the effector function of IgG1 antibodies. Groups have mutated N297 in an effort to make aglycosylated antibodies. The mutations have focuses on substituting N297 with amino acids that resemble asparagine in physiochemical nature such as glutamine (N297Q) or with alanine (N297A) which mimics asparagines without polar groups.

As used herein, “aglycosylated antibody” or “aglycosylated fc” refers to the glycosylation status of the residue at position 297 of the Fc. An antibody or other molecule may contain glycosylation at one or more other locations but may still be considered an aglycosylated antibody or aglcosylated Fc-fusion protein.

In an effort to make effector functionless IgG1 Fc molecules, it was discovered that mutation of amino acid N297 of human IgG1 to glycine, i.e., N297G, provides superior purification efficiency and biophysical properties over other amino acid substitutions at that residue. It was further discovered that antiPAC1 antibodies in an aglycosylated IgG1 framework prevented Fc gamma receptor induced platelet depletion as assessed using a phagocytosis assay (see Example 5) Thus, in preferred embodiments, the anti-PAC1 antibodies comprise antibodies with a “B” or “C” suffix, designating IgG1 aglycosylated variants. In certain embodiments, an antibody comprises the Fc having a N297G substitution.

An Fc comprising a human IgG1 Fc having the N297G mutation may also comprise further insertions, deletions, and substitutions. In certain embodiments the human IgG1 Fc comprises the N297G substitution and is at least 90% identical, at least 91% identical, at least 92% identical, at least 93% identical, at least 94% identical, at least 95% identical, at least 96% identical, at least 97% identical, at least 98% identical, or at least 99% identical to one or more of the amino acid sequences set forth in Table 2B (exemplary anti-hPAC1 Ab heavy chain amino acid sequences).

A glycosylated IgG1 Fc-containing molecules may be less stable than glycosylated IgG1 Fc-containing molecules. The Fc region may thus be further engineered to increase the stability of the aglycosylated molecule. In some embodiments, one or more amino acids are substituted to cysteine so to form di-sulfide bonds in the dimeric state. Residues corresponding to V259, A287, R292, V302, L306, V323, or 1332 of an IgG1 amino acid heavy chain sequence may thus be substituted with cysteine. In preferred embodiments, specific pairs of residues are substitution such that they preferentially form a di-sulfide bond with each other, thus limiting or preventing di-sulfide bond scrambling. Preferred pairs include, but are not limited to, A287C and L306C, V259C and L306C, R292C and V302C, and V323C and I332C.

Specifically exemplified herein are aglycosylated (N297G) IgG1 Fc-containing heavy chains wherein one or both residues 8292 and V302 are substituted with cysteine. The aglycosylated (N297G) IgG1 antibodies with a “C” suffix contain both R292C and V302C substitutions in their heavy chains.

Labels and Effector Groups

In some embodiments, the antigen-binding comprises one or more labels. The term “labeling group” or “label” means any detectable label. Examples of suitable labeling groups include, but are not limited to, the following: radioisotopes or radionuclides (e.g., ³H, ¹⁴C, ¹⁵N, ³⁵S, ⁹⁰Y, ⁹⁹Tc, ¹¹¹In, ¹²⁵I, ¹³¹I), fluorescent groups (e.g., FITC, rhodamine, lanthanide phosphors), enzymatic groups (e.g., horseradish peroxidase, β-galactosidase, luciferase, alkaline phosphatase), chemiluminescent groups, biotinyl groups, or predetermined polypeptide epitopes recognized by a secondary reporter (e.g., leucine zipper pair sequences, binding sites for secondary antibodies, metal binding domains, epitope tags). In some embodiments, the labeling group is coupled to the antibody via spacer arms of various lengths to reduce potential steric hindrance. Various methods for labeling proteins are known in the art and may be used as is seen fit.

The term “effector group” means any group coupled to an antibody that acts as a cytotoxic agent. Examples for suitable effector groups are radioisotopes or radionuclides (e.g., ³H, ¹⁴C, ¹⁵N, ³⁵S, ⁹⁰Y, ⁹⁹Tc, ¹¹¹In, ¹²⁵I, ¹³¹I). Other suitable groups include toxins, therapeutic groups, or chemotherapeutic groups. Examples of suitable groups include calicheamicin, auristatins, geldanamycin and maytansine. In some embodiments, the effector group is coupled to the antibody via spacer arms of various lengths to reduce potential steric hindrance.

In general, labels fall into a variety of classes, depending on the assay in which they are to be detected: a) isotopic labels, which may be radioactive or heavy isotopes; b) magnetic labels (e.g., magnetic particles); c) redox active moieties; d) optical dyes; enzymatic groups (e.g. horseradish peroxidase, β-galactosidase, luciferase, alkaline phosphatase); e) biotinylated groups; and f) predetermined polypeptide epitopes recognized by a secondary reporter (e.g., leucine zipper pair sequences, binding sites for secondary antibodies, metal binding domains, epitope tags, etc.). In some embodiments, the labeling group is coupled to the antibody via spacer arms of various lengths to reduce potential steric hindrance. Various methods for labeling proteins are known in the art.

Specific labels include optical dyes, including, but not limited to, chromophores, phosphors and fluorophores, with the latter being specific in many instances. Fluorophores can be either “small molecule” fluores, or proteinaceous fluores.

By “fluorescent label” is meant any molecule that may be detected via its inherent fluorescent properties. Suitable fluorescent labels include, but are not limited to, fluorescein, rhodamine, tetramethylrhodamine, eosin, erythrosin, coumarin, methyl-coumarins, pyrene, Malacite green, stilbene, Lucifer Yellow, Cascade BlueJ, Texas Red, IAEDANS, EDANS, BODIPY FL, LC Red 640, Cy 5, Cy 5.5, LC Red 705, Oregon green, the Alexa-Fluor dyes (Alexa Fluor 350, Alexa Fluor 430, Alexa Fluor 488, Alexa Fluor 546, Alexa Fluor 568, Alexa Fluor 594, Alexa Fluor 633, Alexa Fluor 647, Alexa Fluor 660, Alexa Fluor 680), Cascade Blue, Cascade Yellow and R-phycoerythrin (PE) (Molecular Probes, Eugene, Oreg.), FITC, Rhodamine, and Texas Red (Pierce, Rockford, Ill.), CyS, Cy5.5, Cy7 (Amersham Life Science, Pittsburgh, Pa.). Suitable optical dyes, including fluorophores, are described in MOLECULAR PROBES HANDBOOK by Richard P. Haugland, hereby expressly incorporated by reference.

Suitable proteinaceous fluorescent labels also include, but are not limited to, green fluorescent protein, including a Renilla, Ptilosarcus, or Aequorea species of GFP (Chalfie et al., 1994, Science 263:802-805), EGFP (Clontech Labs., Inc., Genbank Accession Number U55762), blue fluorescent protein (BFP, Quantum Biotechnologies, Inc., Quebec, Canada; Stauber, 1998, Biotechniques 24:462-471; Heim et al., 1996, Curr. Biol. 6:178-182), enhanced yellow fluorescent protein (EYFP, Clontech Labs., Inc.), luciferase (Ichiki et al., 1993, J. Immunol. 150:5408-5417), β galactosidase (Nolan et al., 1988, Proc. Natl. Acad. Sci. U.S.A. 85:2603-2607) and Renilla (WO92/15673, WO95/07463, WO98/14605, WO98/26277, WO99/49019, U.S. Pat. Nos. 5,292,658, 5,418,155, 5,683,888, 5,741,668, 5,777,079, 5,804,387, 5,874,304, 5,876,995, 5,925,558).

Nucleic Acids

An aspect further provides nucleic acids that hybridize to other nucleic acids (e.g., nucleic acids comprising a nucleotide sequence listed in Tables 1A and 1B under particular hybridization conditions. Methods for hybridizing nucleic acids are well-known in the art. See, e.g., Current Protocols in Molecular Biology, John Wiley & Sons, N.Y. (1989), 6.3.1-6.3.6. As defined herein, a moderately stringent hybridization condition uses a prewashing solution containing 5× sodium chloride/sodium citrate (SSC), 0.5% SDS, 1.0 mM EDTA (pH 8.0), hybridization buffer of about 50% formamide, 6×SSC, and a hybridization temperature of 55° C. (or other similar hybridization solutions, such as one containing about 50% formamide, with a hybridization temperature of 42° C.), and washing conditions of 60° C., in 0.5×SSC, 0.1% SDS. A stringent hybridization condition hybridizes in 6×SSC at 45° C., followed by one or more washes in 0.1×SSC, 0.2% SDS at 68° C. Furthermore, one of skill in the art can manipulate the hybridization and/or washing conditions to increase or decrease the stringency of hybridization such that nucleic acids comprising nucleotide sequences that are at least 65%, 70%, 75%, 80%, 85%, 90%, 95%, 98% or 99% identical to each other typically remain hybridized to each other.

The basic parameters affecting the choice of hybridization conditions and guidance for devising suitable conditions are set forth by, for example, Sambrook, Fritsch, and Maniatis (2001, Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., supra; and Current Protocols in Molecular Biology, 1995, Ausubel et al., eds., John Wiley & Sons, Inc., sections 2.10 and 6.3-6.4), and can be readily determined by those having ordinary skill in the art based on, e.g., the length and/or base composition of the nucleic acid.

Changes can be introduced by mutation into a nucleic acid, thereby leading to changes in the amino acid sequence of a polypeptide (e.g., an antibody or antibody derivative) that it encodes. Mutations can be introduced using any technique known in the art. In one embodiment, one or more particular amino acid residues are changed using, for example, a site-directed mutagenesis protocol. In another embodiment, one or more randomly selected residues is changed using, for example, a random mutagenesis protocol. However it is made, a mutant polypeptide can be expressed and screened for a desired property.

Mutations can be introduced into a nucleic acid without significantly altering the biological activity of a polypeptide that it encodes. For example, one can make nucleotide substitutions leading to amino acid substitutions at non-essential amino acid residues. Alternatively, one or more mutations can be introduced into a nucleic acid that selectively changes the biological activity of a polypeptide that it encodes. For example, the mutation can quantitatively or qualitatively change the biological activity. Examples of quantitative changes include increasing, reducing or eliminating the activity. Examples of qualitative changes include changing the antigen specificity of an antibody. In one embodiment, a nucleic acid encoding any antibody described herein can be mutated to alter the amino acid sequence using molecular biology techniques that are well-established in the art.

Another aspect provides nucleic acid molecules that are suitable for use as primers or hybridization probes for the detection of nucleic acid sequences. A nucleic acid molecule can comprise only a portion of a nucleic acid sequence encoding a full-length polypeptide, for example, a fragment that can be used as a probe or primer or a fragment encoding an active portion (e.g., a PAC1 binding portion) of a polypeptide.

Probes based on the sequence of a nucleic acid can be used to detect the nucleic acid or similar nucleic acids, for example, transcripts encoding a polypeptide. The probe can comprise a label group, e.g., a radioisotope, a fluorescent compound, an enzyme, or an enzyme co-factor. Such probes can be used to identify a cell that expresses the polypeptide.

Another aspect provides vectors comprising a nucleic acid encoding a polypeptide or a portion thereof (e.g., a fragment containing one or more CDRs or one or more variable region domains). Examples of vectors include, but are not limited to, plasmids, viral vectors, non-episomal mammalian vectors and expression vectors, for example, recombinant expression vectors. The recombinant expression vectors can comprise a nucleic acid in a form suitable for expression of the nucleic acid in a host cell. The recombinant expression vectors include one or more regulatory sequences, selected on the basis of the host cells to be used for expression, which is operably linked to the nucleic acid sequence to be expressed. Regulatory sequences include those that direct constitutive expression of a nucleotide sequence in many types of host cells (e.g., SV40 early gene enhancer, Rous sarcoma virus promoter and cytomegalovirus promoter), those that direct expression of the nucleotide sequence only in certain host cells (e.g., tissue-specific regulatory sequences, see, Voss et al., 1986, Trends Biochem. Sci. 11:287, Maniatis et al., 1987, Science 236:1237, incorporated by reference herein in their entireties), and those that direct inducible expression of a nucleotide sequence in response to particular treatment or condition (e.g., the metallothionin promoter in mammalian cells and the tet-responsive and/or streptomycin responsive promoter in both prokaryotic and eukaryotic systems (see, id.). It will be appreciated by those skilled in the art that the design of the expression vector can depend on such factors as the choice of the host cell to be transformed, the level of expression of protein desired, etc. The expression vectors can be introduced into host cells to thereby produce proteins or peptides, including fusion proteins or peptides, encoded by nucleic acids as described herein.

Another aspect provides host cells into which a recombinant expression vector has been introduced. A host cell can be any prokaryotic cell (for example, E. coli) or eukaryotic cell (for example, yeast, insect, or mammalian cells (e.g., CHO cells)). Vector DNA can be introduced into prokaryotic or eukaryotic cells via conventional transformation or transfection techniques. For stable transfection of mammalian cells, it is known that, depending upon the expression vector and transfection technique used, only a small fraction of cells may integrate the foreign DNA into their genome. In order to identify and select these integrants, a gene that encodes a selectable marker (e.g., for resistance to antibiotics) is generally introduced into the host cells along with the gene of interest. Preferred selectable markers include those which confer resistance to drugs, such as G418, hygromycin and methotrexate. Cells stably transfected with the introduced nucleic acid can be identified by drug selection (e.g., cells that have incorporated the selectable marker gene will survive, while the other cells die), among other methods.

Preparing Antibodies

Non-human antibodies that are provided can be, for example, derived from any antibody-producing animal, such as mouse, rat, rabbit, goat, donkey, or non-human primate (such as monkey (e.g., cynomolgus or rhesus monkey) or ape (e.g., chimpanzee)). Non-human antibodies can be used, for instance, in in vitro cell culture and cell-culture based applications, or any other application where an immune response to the antibody does not occur or is insignificant, can be prevented, is not a concern, or is desired. In certain embodiments, the antibodies may be produced by immunizing animals using methods known in the art, as described above. The antibodies may be polyclonal, monoclonal, or may be synthesized in host cells by expressing recombinant DNA. Fully human antibodies may be prepared as described above by immunizing transgenic animals containing human immunoglobulin loci or by selecting a phage display library that is expressing a repertoire of human antibodies.

The monoclonal antibodies (mAbs) can be produced by a variety of techniques, including conventional monoclonal antibody methodology, e.g., the standard somatic cell hybridization technique of Kohler and Milstein, 1975, Nature 256:495. Alternatively, other techniques for producing monoclonal antibodies can be employed, for example, the viral or oncogenic transformation of B-lymphocytes. One suitable animal system for preparing hybridomas is the murine system, which is a very well established procedure Immunization protocols and techniques for isolation of immunized splenocytes for fusion are known in the art and illustrative approaches are described in the Examples, below. For such procedures, B cells from immunized mice are typically fused with a suitable immortalized fusion partner, such as a murine myeloma cell line. If desired, rats or other mammals besides can be immunized instead of mice and B cells from such animals can be fused with the murine myeloma cell line to form hybridomas. Alternatively, a myeloma cell line from a source other than mouse may be used. Fusion procedures for making hybridomas also are well known.

The single chain antibodies that are provided may be formed by linking heavy and light chain variable domain (Fv region) fragments via an amino acid bridge (short peptide linker), resulting in a single polypeptide chain. Such single-chain Fvs (scFvs) may be prepared by fusing DNA encoding a peptide linker between DNAs encoding the two variable domain polypeptides (V_(L) and V_(H)). The resulting polypeptides can fold back on themselves to form antigen-binding monomers, or they can form multimers (e.g., dimers, trimers, or tetramers), depending on the length of a flexible linker between the two variable domains (Kortt et al., 1997, Prot. Eng. 10:423; Kortt et al., 2001, Biomol. Eng. 18:95-108). By combining different V_(L) and V_(H)-comprising polypeptides, one can form multimeric scFvs that bind to different epitopes (Kriangkum et al., 2001, Biomol. Eng. 18:31-40). Techniques developed for the production of single chain antibodies include those described in U.S. Pat. No. 4,946,778; Bird, 1988, Science 242:423; Huston et al., 1988, Proc. Natl. Acad. Sci. U.S.A. 85:5879; Ward et al., 1989, Nature 334:544, de Graaf et al., 2002, Methods Mol Biol. 178:379-387. Single chain antibodies derived from antibodies provided herein include, but are not limited to scFvs comprising the variable domain combinations of the heavy and light chain variable regions depicted in Tables 3A and 3B, or combinations of light and heavy chain variable domains which include CDRs depicted in Tables 4A and 4B.

Antibodies provided herein that are of one subclass can be changed to antibodies from a different subclass using subclass switching methods. Thus, IgG antibodies may be derived from an IgM antibody, for example, and vice versa. Such techniques allow the preparation of new antibodies that possess the antigen binding properties of a given antibody (the parent antibody), but also exhibit biological properties associated with an antibody isotype or subclass different from that of the parent antibody. Recombinant DNA techniques may be employed. Cloned DNA encoding particular antibody polypeptides may be employed in such procedures, e.g., DNA encoding the constant domain of an antibody of the desired isotype. See, e.g., Lantto et al., 2002, Methods Mol. Biol. 178:303-316.

Accordingly, the antibodies that are provided include those comprising, for example, the variable domain combinations described, supra., having a desired isotype (for example, IgA, IgG1, IgG2, IgG3, IgG4, IgE, and IgD) as well as Fab or F(ab′)₂ fragments thereof. Moreover, if an IgG4 is desired, it may also be desired to introduce a point mutation (CPSCP->CPPCP) in the hinge region as described in Bloom et al., 1997, Protein Science 6:407, incorporated by reference herein) to alleviate a tendency to form intra-H chain disulfide bonds that can lead to heterogeneity in the IgG4 antibodies.

Moreover, techniques for deriving antibodies having different properties (i.e., varying affinities for the antigen to which they bind) are also known. One such technique, referred to as chain shuffling, involves displaying immunoglobulin variable domain gene repertoires on the surface of filamentous bacteriophage, often referred to as phage display. Chain shuffling has been used to prepare high affinity antibodies to the hapten 2-phenyloxazol-5-one, as described by Marks et al., 1992, BioTechnology 10:779.

Conservative modifications may be made to the heavy and light chain variable regions described in Tables 3A and 3B, or the CDRs described in Tables 4A and 4B (and corresponding modifications to the encoding nucleic acids) to produce a PAC1 binding protein having certain desirable functional and biochemical characteristics. Methods for achieving such modifications are described above.

PAC1 antibodies may be further modified in various ways. For example, if they are to be used for therapeutic purposes, they may be conjugated with polyethylene glycol (pegylated) to prolong the serum half-life or to enhance protein delivery. Alternatively, the V region of the subject antibodies or fragments thereof may be fused with the Fc region of a different antibody molecule. The Fc region used for this purpose may be modified so that it does not bind complement, thus reducing the likelihood of inducing cell lysis in the patient when the fusion protein is used as a therapeutic agent. In addition, the subject antibodies or functional fragments thereof may be conjugated with human serum albumin to enhance the serum half-life of the antibody or antigen binding fragment thereof. Another useful fusion partner for the antibodies or fragments thereof is transthyretin (TTR). TTR has the capacity to form a tetramer, thus an antibody-TTR fusion protein can form a multivalent antibody which may increase its binding avidity.

Alternatively, substantial modifications in the functional and/or biochemical characteristics of the antibodies described herein may be achieved by creating substitutions in the amino acid sequence of the heavy and light chains that differ significantly in their effect on maintaining (a) the structure of the molecular backbone in the area of the substitution, for example, as a sheet or helical conformation, (b) the charge or hydrophobicity of the molecule at the target site, or (c) the bulkiness of the side chain. A “conservative amino acid substitution” may involve a substitution of a native amino acid residue with a nonnative residue that has little or no effect on the polarity or charge of the amino acid residue at that position. See, Table 6, supra. Furthermore, any native residue in the polypeptide may also be substituted with alanine, as has been previously described for alanine scanning mutagenesis.

Amino acid substitutions (whether conservative or non-conservative) of the subject antibodies can be implemented by those skilled in the art by applying routine techniques. Amino acid substitutions can be used to identify important residues of the antibodies provided herein, or to increase or decrease the affinity of these antibodies for human PAC1 or for modifying the binding affinity of other antibodies described herein.

Methods Of Expressing Antibodies

Expression systems and constructs in the form of plasmids, expression vectors, transcription or expression cassettes that comprise at least one polynucleotide as described above are also provided herein, as well host cells comprising such expression systems or constructs.

The antibodies provided herein may be prepared by any of a number of conventional techniques. For example, PAC1 antibodies may be produced by recombinant expression systems, using any technique known in the art. See, e.g., Monoclonal Antibodies, Hybridomas: A New Dimension in Biological Analyses, Kennet et al. (eds.) Plenum Press, New York (1980); and Antibodies: A Laboratory Manual, Harlow and Lane (eds.), Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y. (1988).

Antibodies can be expressed in hybridoma cell lines (e.g., in particular antibodies may be expressed in hybridomas) or in cell lines other than hybridomas. Expression constructs encoding the antibodies can be used to transform a mammalian, insect or microbial host cell. Transformation can be performed using any known method for introducing polynucleotides into a host cell, including, for example packaging the polynucleotide in a virus or bacteriophage and transducing a host cell with the construct by transfection procedures known in the art, as exemplified by U.S. Pat. Nos. 4,399,216; 4,912,040; 4,740,461; 4,959,455. The optimal transformation procedure used will depend upon which type of host cell is being transformed. Methods for introduction of heterologous polynucleotides into mammalian cells are well known in the art and include, but are not limited to, dextran-mediated transfection, calcium phosphate precipitation, polybrene mediated transfection, protoplast fusion, electroporation, encapsulation of the polynucleotide(s) in liposomes, mixing nucleic acid with positively-charged lipids, and direct microinjection of the DNA into nuclei.

Recombinant expression constructs typically comprise a nucleic acid molecule encoding a polypeptide comprising one or more of the following: one or more CDRs provided herein; a light chain constant region; a light chain variable region; a heavy chain constant region (e.g., C_(H)1, C_(H)2 and/or C_(H)3); and/or another scaffold portion of a PAC1 antibody. These nucleic acid sequences are inserted into an appropriate expression vector using standard ligation techniques. In one embodiment, the heavy or light chain constant region is appended to the C-terminus of the anti-PAC1-specific heavy or light chain variable region and is ligated into an expression vector. The vector is typically selected to be functional in the particular host cell employed (i.e., the vector is compatible with the host cell machinery, permitting amplification and/or expression of the gene can occur). In some embodiments, vectors are used that employ protein-fragment complementation assays using protein reporters, such as dihydrofolate reductase (see, for example, U.S. Pat. No. 6,270,964, which is hereby incorporated by reference). Suitable expression vectors can be purchased, for example, from Invitrogen Life Technologies or BD Biosciences (formerly “Clontech”). Other useful vectors for cloning and expressing the antibodies and fragments include those described in Bianchi and McGrew, 2003, Biotech. Biotechnol. Bioeng. 84:439-44, which is hereby incorporated by reference. Additional suitable expression vectors are discussed, for example, in Methods Enzymol., vol. 185 (D. V. Goeddel, ed.), 1990, New York: Academic Press.

Typically, expression vectors used in any of the host cells will contain sequences for plasmid maintenance and for cloning and expression of exogenous nucleotide sequences. Such sequences, collectively referred to as “flanking sequences” in certain embodiments will typically include one or more of the following nucleotide sequences: a promoter, one or more enhancer sequences, an origin of replication, a transcriptional termination sequence, a complete intron sequence containing a donor and acceptor splice site, a sequence encoding a leader sequence for polypeptide secretion, a ribosome binding site, a polyadenylation sequence, a polylinker region for inserting the nucleic acid encoding the polypeptide to be expressed, and a selectable marker element. Each of these sequences is discussed below.

Optionally, the vector may contain a “tag”-encoding sequence, i.e., an oligonucleotide molecule located at the 5′ or 3′ end of the PAC1 binding protein coding sequence; the oligonucleotide sequence encodes polyHis (such as hexaHis), or another “tag” such as FLAG®, HA (hemaglutinin influenza virus), or myc, for which commercially available antibodies exist. This tag is typically fused to the polypeptide upon expression of the polypeptide, and can serve as a means for affinity purification or detection of the PAC1 binding protein from the host cell. Affinity purification can be accomplished, for example, by column chromatography using antibodies against the tag as an affinity matrix. Optionally, the tag can subsequently be removed from the purified PAC1 binding protein by various means such as using certain peptidases for cleavage.

Flanking sequences may be homologous (i.e., from the same species and/or strain as the host cell), heterologous (i.e., from a species other than the host cell species or strain), hybrid (i.e., a combination of flanking sequences from more than one source), synthetic or native. As such, the source of a flanking sequence may be any prokaryotic or eukaryotic organism, any vertebrate or invertebrate organism, or any plant, provided that the flanking sequence is functional in, and can be activated by, the host cell machinery.

Flanking sequences useful in the vectors may be obtained by any of several methods well known in the art. Typically, flanking sequences useful herein will have been previously identified by mapping and/or by restriction endonuclease digestion and can thus be isolated from the proper tissue source using the appropriate restriction endonucleases. In some cases, the full nucleotide sequence of a flanking sequence may be known. Here, the flanking sequence may be synthesized using the methods described herein for nucleic acid synthesis or cloning.

Whether all or only a portion of the flanking sequence is known, it may be obtained using polymerase chain reaction (PCR) and/or by screening a genomic library with a suitable probe such as an oligonucleotide and/or flanking sequence fragment from the same or another species. Where the flanking sequence is not known, a fragment of DNA containing a flanking sequence may be isolated from a larger piece of DNA that may contain, for example, a coding sequence or even another gene or genes. Isolation may be accomplished by restriction endonuclease digestion to produce the proper DNA fragment followed by isolation using agarose gel purification, Qiagen® column chromatography (Chatsworth, Calif.), or other methods known to the skilled artisan. The selection of suitable enzymes to accomplish this purpose will be readily apparent to one of ordinary skill in the art.

An origin of replication is typically a part of those prokaryotic expression vectors purchased commercially, and the origin aids in the amplification of the vector in a host cell. If the vector of choice does not contain an origin of replication site, one may be chemically synthesized based on a known sequence, and ligated into the vector. For example, the origin of replication from the plasmid pBR322 (New England Biolabs, Beverly, Mass.) is suitable for most gram-negative bacteria, and various viral origins (e.g., SV40, polyoma, adenovirus, vesicular stomatitus virus (VSV), or papillomaviruses such as HPV or BPV) are useful for cloning vectors in mammalian cells. Generally, the origin of replication component is not needed for mammalian expression vectors (for example, the SV40 origin is often used only because it also contains the virus early promoter).

A transcription termination sequence is typically located 3′ to the end of a polypeptide coding region and serves to terminate transcription. Usually, a transcription termination sequence in prokaryotic cells is a G-C rich fragment followed by a poly-T sequence. While the sequence is easily cloned from a library or even purchased commercially as part of a vector, it can also be readily synthesized using methods for nucleic acid synthesis such as those described herein.

A selectable marker gene encodes a protein necessary for the survival and growth of a host cell grown in a selective culture medium. Typical selection marker genes encode proteins that (a) confer resistance to antibiotics or other toxins, e.g., ampicillin, tetracycline, or kanamycin for prokaryotic host cells; (b) complement auxotrophic deficiencies of the cell; or (c) supply critical nutrients not available from complex or defined media. Specific selectable markers are the kanamycin resistance gene, the ampicillin resistance gene, and the tetracycline resistance gene. Advantageously, a neomycin resistance gene may also be used for selection in both prokaryotic and eukaryotic host cells.

Other selectable genes may be used to amplify the gene that will be expressed. Amplification is the process wherein genes that are required for production of a protein critical for growth or cell survival are reiterated in tandem within the chromosomes of successive generations of recombinant cells. Examples of suitable selectable markers for mammalian cells include dihydrofolate reductase (DHFR) and promoterless thymidine kinase genes. Mammalian cell transformants are placed under selection pressure wherein only the transformants are uniquely adapted to survive by virtue of the selectable gene present in the vector. Selection pressure is imposed by culturing the transformed cells under conditions in which the concentration of selection agent in the medium is successively increased, thereby leading to the amplification of both the selectable gene and the DNA that encodes another gene, such as an antibody that binds to PAC1. As a result, increased quantities of a polypeptide such as an antibody are synthesized from the amplified DNA.

A ribosome-binding site is usually necessary for translation initiation of mRNA and is characterized by a Shine-Dalgarno sequence (prokaryotes) or a Kozak sequence (eukaryotes). The element is typically located 3′ to the promoter and 5′ to the coding sequence of the polypeptide to be expressed.

In some cases, such as where glycosylation is desired in a eukaryotic host cell expression system, one may manipulate the various pre- or pro-sequences to improve glycosylation or yield. For example, one may alter the peptidase cleavage site of a particular signal peptide, or add prosequences, which also may affect glycosylation. The final protein product may have, in the −1 position (relative to the first amino acid of the mature protein), one or more additional amino acids incident to expression, which may not have been totally removed. For example, the final protein product may have one or two amino acid residues found in the peptidase cleavage site, attached to the amino-terminus. Alternatively, use of some enzyme cleavage sites may result in a slightly truncated form of the desired polypeptide, if the enzyme cuts at such area within the mature polypeptide.

Expression and cloning will typically contain a promoter that is recognized by the host organism and operably linked to the molecule encoding a PAC1 binding protein. Promoters are untranscribed sequences located upstream (i.e., 5′) to the start codon of a structural gene (generally within about 100 to 1000 bp) that control transcription of the structural gene. Promoters are conventionally grouped into one of two classes: inducible promoters and constitutive promoters. Inducible promoters initiate increased levels of transcription from DNA under their control in response to some change in culture conditions, such as the presence or absence of a nutrient or a change in temperature. Constitutive promoters, on the other hand, uniformly transcribe a gene to which they are operably linked, that is, with little or no control over gene expression. A large number of promoters, recognized by a variety of potential host cells, are well known. A suitable promoter is operably linked to the DNA encoding heavy chain or light chain comprising a PAC1 binding protein by removing the promoter from the source DNA by restriction enzyme digestion and inserting the desired promoter sequence into the vector.

Suitable promoters for use with yeast hosts are also well known in the art. Yeast enhancers are advantageously used with yeast promoters. Suitable promoters for use with mammalian host cells are well known and include, but are not limited to, those obtained from the genomes of viruses such as polyoma virus, fowlpox virus, adenovirus (such as Adenovirus 2), bovine papilloma virus, avian sarcoma virus, cytomegalovirus, retroviruses, hepatitis-B virus, and Simian Virus 40 (SV40). Other suitable mammalian promoters include heterologous mammalian promoters, for example, heat-shock promoters and the actin promoter.

Natl. Acad. Sci. U.S.A. 75:3727-3731); or the tac promoter (DeBoer et al., 1983, Proc. Natl. Acad. Sci. U.S.A. 80:21-25). Also of interest are the following animal transcriptional control regions, which exhibit tissue specificity and have been utilized in transgenic animals: the elastase I gene control region that is active in pancreatic acinar cells (Swift et al., 1984, Cell 38:639-646; Ornitz et al., 1986, Cold Spring Harbor Symp. Quant. Biol. 50:399-409; MacDonald, 1987, Hepatology 7:425-515); the insulin gene control region that is active in pancreatic beta cells (Hanahan, 1985, Nature 315:115-122); the immunoglobulin gene control region that is active in lymphoid cells (Grosschedl et al., 1984, Cell 38:647-658; Adames et al., 1985, Nature 318:533-538; Alexander et al., 1987, Mol. Cell.

Cell. Biol. 5:1639-1648; Hammer et al., 1987, Science 253:53-58); the alpha 1-antitrypsin gene control region that is active in liver (Kelsey et al., 1987, Genes and Devel. 1:161-171); the beta-globin gene control region that is active in myeloid cells (Mogram et al., 1985, Nature 315:338-340; Kollias et al., 1986, Cell 46:89-94); the myelin basic protein gene control region that is active in oligodendrocyte cells in the brain (Readhead et al., 1987, Cell 48:703-712); the myosin light chain-2 gene control region that is active in skeletal muscle (Sani, 1985, Nature 314:283-286); and the gonadotropic releasing hormone gene control region that is active in the hypothalamus (Mason et al., 1986, Science 234:1372-1378).

An enhancer sequence may be inserted into the vector to increase transcription of DNA encoding light chain or heavy chain comprising a human PAC1 binding protein by higher eukaryotes. Enhancers are cis-acting elements of DNA, usually about 10-300 bp in length, that act on the promoter to increase transcription. Enhancers are relatively orientation and position independent, having been found at positions both 5′ and 3′ to the transcription unit. Several enhancer sequences available from mammalian genes are known (e.g., globin, elastase, albumin, alpha-feto-protein and insulin). Typically, however, an enhancer from a virus is used. The SV40 enhancer, the cytomegalovirus early promoter enhancer, the polyoma enhancer, and adenovirus enhancers known in the art are exemplary enhancing elements for the activation of eukaryotic promoters. While an enhancer may be positioned in the vector either 5′ or 3′ to a coding sequence, it is typically located at a site 5′ from the promoter. A sequence encoding an appropriate native or heterologous signal sequence (leader sequence or signal peptide) can be incorporated into an expression vector, to promote extracellular secretion of the antibody. The choice of signal peptide or leader depends on the type of host cells in which the antibody is to be produced, and a heterologous signal sequence can replace the native signal sequence. Examples of signal peptides that are functional in mammalian host cells include the following: the signal sequence for interleukin-7 (IL-7) described in U.S. Pat. No. 4,965,195; the signal sequence for interleukin-2 receptor described in Cosman et al., 1984, Nature 312:768; the interleukin-4 receptor signal peptide described in EP Patent No. 0367 566; the type I interleukin-1 receptor signal peptide described in U.S. Pat. No. 4,968,607; the type II interleukin-1 receptor signal peptide described in EP Patent No. 0 460 846.

The expression vectors that are provided may be constructed from a starting vector such as a commercially available vector. Such vectors may or may not contain all of the desired flanking sequences. Where one or more of the flanking sequences described herein are not already present in the vector, they may be individually obtained and ligated into the vector. Methods used for obtaining each of the flanking sequences are well known to one skilled in the art.

After the vector has been constructed and a nucleic acid molecule encoding light chain, a heavy chain, or a light chain and a heavy chain comprising a PAC1 antigen binding sequence has been inserted into the proper site of the vector, the completed vector may be inserted into a suitable host cell for amplification and/or polypeptide expression. The transformation of an expression vector for an antibody into a selected host cell may be accomplished by well known methods including transfection, infection, calcium phosphate co-precipitation, electroporation, microinjection, lipofection, DEAE-dextran mediated transfection, or other known techniques. The method selected will in part be a function of the type of host cell to be used. These methods and other suitable methods are well known to the skilled artisan, and are set forth, for example, in Sambrook et al., 2001, supra.

A host cell, when cultured under appropriate conditions, synthesizes an antibody that can subsequently be collected from the culture medium (if the host cell secretes it into the medium) or directly from the host cell producing it (if it is not secreted). The selection of an appropriate host cell will depend upon various factors, such as desired expression levels, polypeptide modifications that are desirable or necessary for activity (such as glycosylation or phosphorylation) and ease of folding into a biologically active molecule.

Mammalian cell lines available as hosts for expression are well known in the art and include, but are not limited to, immortalized cell lines available from the American Type Culture Collection (ATCC), including but not limited to Chinese hamster ovary (CHO) cells, HeLa cells, baby hamster kidney (BHK) cells, monkey kidney cells (COS), human hepatocellular carcinoma cells (e.g., Hep G2), and a number of other cell lines. In certain embodiments, cell lines may be selected through determining which cell lines have high expression levels and constitutively produce antibodies with PAC1 binding properties. In another embodiment, a cell line from the B cell lineage that does not make its own antibody but has a capacity to make and secrete a heterologous antibody can be selected.

Use of Human PAC1 Antibodies for Diagnostic and Therapeutic Purposes

Antibodies are useful for detecting PAC1 in biological samples and identification of cells or tissues that produce PAC1. For instance, the PAC1 antibodies can be used in diagnostic assays, e.g., binding assays to detect and/or quantify PAC1 expressed in a tissue or cell. Antibodies that specifically bind to PAC1 can also be used in treatment of diseases related to PAC1 in a patient in need thereof. In addition, PAC1 antibodies can be used to inhibit PAC1 from forming a complex with its ligand PACAP (e.g., PACAP-38), thereby modulating the biological activity of PAC1 in a cell or tissue. Examples of activities that can be modulated include, but are not limited to, inhibiting vasodialation and/or decrease neurogenic inflammation. Antibodies that bind to PAC1 thus can modulate and/or block interaction with other binding compounds and as such may have therapeutic use in ameliorating diseases related to PAC1.

Indications

A disease or condition associated with human PAC1 includes any disease or condition whose onset in a patient is caused by, at least in part, the interaction of PAC1 with its ligand, PACAP (e.g., PACAP-38). The severity of the disease or condition can also be increased or decreased by the interaction of PAC1 with PACAP (e.g., PACAP-38). Examples of diseases and conditions that can be treated with the antibodies described herein include headaches, such as cluster headaches, migraine, including migraine headaches, chronic pain, type II diabetes mellitus, inflammation, e.g., neurogenic inflammation, cardiovascular disorders, and hemodynamic derangement associated with endotoxemia and sepsis.

In particular, antibodies described herein can be used to treat migraine, either as an acute treatment commencing after a migraine attack has commenced, and/or as a prophylactic treatment administered, e.g., daily, weekly, biweekly, monthly, bimonthly, biannually, etc.) to prevent or reduce the frequency and/or severity of symptoms, e.g., pain symptoms, associated with migraine attacks.

Infusion of the PAC1 receptor agonist PACAP causes migraine-like headache in migraine patients, suggesting that blocking PAC1 may be useful for treating migraine. Immunohistochemistry studies in cynomolgus monkey performed in support of the present invention mapped PACAP and PAC1 localization to the parasympathetic pathway through the sphenopalatine ganglion (SPG; also known as pterygopalatine ganglion), which also innervates the dura vasculature. The parasympathetic pathway is independent and parallel to the sensory pathway that also controls the dura vasculature tone, hence likely plays a role in migraine pathophysiology. Additional experiments performed in support of the present invention showed that a selective PAC1 Ab blocked electrically stimulated trigeminal cervical complex (TCC) activation, an electrophysiology model that has been reported to correlate with clinical migraine efficacy. Taken together, the evidence supports the targeting of PAC1 with a selective antagonist such as an anti-PAC1 antibody as described herein to treat migraine. The expected efficacy of an anti-PAC1 therapeutic for the treatment of migraine in human patients is further supported by published papers, including, for example Schytz, H. W., et al., “The PACAP receptor: a novel target for migraine treatment.”, Neurotherapeutics. 2010 April;7(2):191-6; Olesen J., et al., “Emerging migraine treatments and drug targets”, Trends Pharmacol Sci. 2011 June;32(6):352-9; and Schytz, H. W., et al., “PACAP38 induces migraine-like attacks in patients with migraine without aura”, Brain (2009) 132 (1): 16-25.

Cluster headache is a condition that involves, as its most prominent feature, an one-sided, immense degree of pain. Some doctors and scientists have described the pain resulting from cluster headaches as the most intense pain a human can endure—worse than giving birth, burns or broken bones. Cluster headaches often occur periodically: spontaneous remissions interrupt active periods of pain. The average age of onset of cluster headache is ˜30-50 years. It is more prevalent in males with a male to female ratio varies 2.5:1 or 3.5:1. SPG stimulation has been used for the treatment of cluster headache. Most recently, Autonomic Technologies has developed the ATI™ Neurostimulation System to deliver low-level (but high frequency, physiologic-blocking) electrical stimulation to provide acute SPG stimulation therapy with the intention to relieve the acute debilitating pain of cluster headache. A robust efficacy has been demonstrated in their recent clinical trial (NCT01616511; Schoenen J, et al., “Stimulation of the sphenopalatine ganglion (SPG) for cluster headache treatment. Pathway CH-1: A randomized, sham-controlled study.”, Cephalalgia. 2013;33(10):816-30. In view of the above and because PACAP is one of the major neurotransmitters in SPG, a PAC1 receptor antagonist such as an anti-PAC1 antibody described herein is expected to have efficacy to treat cluster headache in humans.

Diagnostic Methods

The antibodies described herein can be used for diagnostic purposes to detect, diagnose, or monitor diseases and/or conditions associated with PAC1. Also provided are methods for the detection of the presence of PAC1 in a sample using classical immunohistological methods known to those of skill in the art (e.g., Tijssen, 1993, Practice and Theory of Enzyme Immunoassays, Vol 15 (Eds R. H. Burdon and P. H. van Knippenberg, Elsevier, Amsterdam); Zola, 1987, Monoclonal Antibodies: A Manual of Techniques, pp. 147-158 (CRC Press, Inc.); Jalkanen et al., 1985, J Cell. Biol. 101:976-985; Jalkanen et al., 1987, J. Cell Biol. 105:3087-3096). The detection of PAC1 can be performed in vivo or in vitro.

Diagnostic applications provided herein include use of the antibodies to detect expression of PAC1 and binding of the ligands to PAC1. Examples of methods useful in the detection of the presence of PAC1 include immunoassays, such as the enzyme linked immunosorbent assay (ELISA) and the radioimmunoassay (RIA).

For diagnostic applications, the antibody typically will be labeled with a detectable labeling group. Suitable labeling groups include, but are not limited to, the following: radioisotopes or radionuclides (e.g., ³H, ¹⁴C, ¹⁵N, ³⁵S, ⁹⁰Y, ⁹⁹Tc, ¹¹¹In, ¹²⁵I, ¹³¹I) fluorescent groups (e.g., FITC, rhodamine, lanthanide phosphors), enzymatic groups (e.g., horseradish peroxidase, β-galactosidase, luciferase, alkaline phosphatase), chemiluminescent groups, biotinyl groups, or predetermined polypeptide epitopes recognized by a secondary reporter (e.g., leucine zipper pair sequences, binding sites for secondary antibodies, metal binding domains, epitope tags). In some embodiments, the labeling group is coupled to the antibody via spacer arms of various lengths to reduce potential steric hindrance. Various methods for labeling proteins are known in the art and may be used.

In another aspect, an antibody can be used to identify a cell or cells that express PAC1. In a specific embodiment, the antibody is labeled with a labeling group and the binding of the labeled antibody to PAC1 is detected. In a further specific embodiment, the binding of the antibody to PAC1 detected in vivo. In a further specific embodiment, the PAC1 antibody is isolated and measured using techniques known in the art. See, for example, Harlow and Lane, 1988, Antibodies: A Laboratory Manual, New York: Cold Spring Harbor (ed. 1991 and periodic supplements); John E. Coligan, ed., 1993, Current Protocols In Immunology New York: John Wiley & Sons.

Another aspect provides for detecting the presence of a test molecule that competes for binding to PAC1 with the antibodies provided. An example of one such assay would involve detecting the amount of free antibody in a solution containing an amount of PAC1 in the presence or absence of the test molecule. An increase in the amount of free antibody (i.e., the antibody not bound to PAC1) would indicate that the test molecule is capable of competing for PAC1 binding with the antibody. In one embodiment, the antibody is labeled with a labeling group. Alternatively, the test molecule is labeled and the amount of free test molecule is monitored in the presence and absence of an antibody.

Methods of Treatment: Pharmaceutical Formulations, Routes of Administration

Methods of using the antibodies are also provided. In some methods, an antibody is provided to a patient. The antibody inhibits binding of PACAP to human PAC1.

Pharmaceutical compositions that comprise a therapeutically effective amount of one or a plurality of the antibodies and a pharmaceutically acceptable diluent, carrier, solubilizer, emulsifier, preservative, and/or adjuvant are also provided. In addition, methods of treating a patient, e.g., for migraine, by administering such pharmaceutical composition are included. The term “patient” includes human patients.

Acceptable formulation materials are nontoxic to recipients at the dosages and concentrations employed. In specific embodiments, pharmaceutical compositions comprising a therapeutically effective amount of human PAC1 antibodies are provided.

In certain embodiments, acceptable formulation materials preferably are nontoxic to recipients at the dosages and concentrations employed. In certain embodiments, the pharmaceutical composition may contain formulation materials for modifying, maintaining or preserving, for example, the pH, osmolarity, viscosity, clarity, color, isotonicity, odor, sterility, stability, rate of dissolution or release, adsorption or penetration of the composition. In such embodiments, suitable formulation materials include, but are not limited to, amino acids (such as glycine, glutamine, asparagine, arginine or lysine); antimicrobials; antioxidants (such as ascorbic acid, sodium sulfite or sodium hydrogen-sulfite); buffers (such as borate, bicarbonate, Tris-HCl, citrates, phosphates or other organic acids); bulking agents (such as mannitol or glycine); chelating agents (such as ethylenediamine tetraacetic acid (EDTA)); complexing agents (such as caffeine, polyvinylpyrrolidone, beta-cyclodextrin or hydroxypropyl-beta-cyclodextrin); fillers; monosaccharides; disaccharides; and other carbohydrates (such as glucose, mannose or dextrins); proteins (such as serum albumin, gelatin or immunoglobulins); coloring, flavoring and diluting agents; emulsifying agents; hydrophilic polymers (such as polyvinylpyrrolidone); low molecular weight polypeptides; salt-forming counterions (such as sodium); preservatives (such as benzalkonium chloride, benzoic acid, salicylic acid, thimerosal, phenethyl alcohol, methylparaben, propylparaben, chlorhexidine, sorbic acid or hydrogen peroxide); solvents (such as glycerin, propylene glycol or polyethylene glycol); sugar alcohols (such as mannitol or sorbitol); suspending agents; surfactants or wetting agents (such as pluronics, PEG, sorbitan esters, polysorbates such as polysorbate 20, polysorbate, triton, tromethamine, lecithin, cholesterol, tyloxapal); stability enhancing agents (such as sucrose or sorbitol); tonicity enhancing agents (such as alkali metal halides, preferably sodium or potassium chloride, mannitol sorbitol); delivery vehicles; diluents; excipients and/or pharmaceutical adjuvants. See, REMINGTON'S PHARMACEUTICAL SCIENCES, 18″ Edition, (A. R. Genrmo, ed.), 1990, Mack Publishing Company.

In certain embodiments, the optimal pharmaceutical composition will be determined by one skilled in the art depending upon, for example, the intended route of administration, delivery format and desired dosage. See, for example, REMINGTON'S PHARMACEUTICAL SCIENCES, supra. In certain embodiments, such compositions may influence the physical state, stability, rate of in vivo release and rate of in vivo clearance of the antibodies disclosed. In certain embodiments, the primary vehicle or carrier in a pharmaceutical composition may be either aqueous or non-aqueous in nature. For example, a suitable vehicle or carrier may be water for injection, physiological saline solution or artificial cerebrospinal fluid, possibly supplemented with other materials common in compositions for parenteral administration. Neutral buffered saline or saline mixed with serum albumin are further exemplary vehicles. In specific embodiments, pharmaceutical compositions comprise Tris buffer of about pH 7.0-8.5, or acetate buffer of about pH 4.0-5.5, and may further include sorbitol or a suitable substitute. In certain embodiments, human PAC1 antibody compositions may be prepared for storage by mixing the selected composition having the desired degree of purity with optional formulation agents (REMINGTON'S PHARMACEUTICAL SCIENCES, supra) in the form of a lyophilized cake or an aqueous solution. Further, in certain embodiments, the human PAC1 antibody may be formulated as a lyophilizate using appropriate excipients such as sucrose.

The pharmaceutical compositions can be selected for parenteral delivery. Alternatively, the compositions may be selected for inhalation or for delivery through the digestive tract, such as orally. Preparation of such pharmaceutically acceptable compositions is within the skill of the art.

The formulation components are present preferably in concentrations that are acceptable to the site of administration. In certain embodiments, buffers are used to maintain the composition at physiological pH or at a slightly lower pH, typically within a pH range of from about 5 to about 8.

When parenteral administration is contemplated, the therapeutic compositions may be provided in the form of a pyrogen-free, parenterally acceptable aqueous solution comprising the desired human PAC1 binding protein in a pharmaceutically acceptable vehicle. A particularly suitable vehicle for parenteral injection is sterile distilled water in which the human PAC1 antibody is formulated as a sterile, isotonic solution, properly preserved. In certain embodiments, the preparation can involve the formulation of the desired molecule with an agent, such as injectable microspheres, bio-erodible particles, polymeric compounds (such as polylactic acid or polyglycolic acid), beads or liposomes, that may provide controlled or sustained release of the product which can be delivered via depot injection. In certain embodiments, hyaluronic acid may also be used, having the effect of promoting sustained duration in the circulation. In certain embodiments, implantable drug delivery devices may be used to introduce the desired antibody.

Certain pharmaceutical compositions are formulated for inhalation. In some embodiments, human PAC1 antibodies are formulated as a dry, inhalable powder. In specific embodiments, human PAC1 antibody inhalation solutions may also be formulated with a propellant for aerosol delivery. In certain embodiments, solutions may be nebulized. Pulmonary administration and formulation methods therefore are further described in International Patent Application No. PCT/US94/001875, which is incorporated by reference and describes pulmonary delivery of chemically modified proteins. Some formulations can be administered orally. Human PAC1 antibodies that are administered in this fashion can be formulated with or without carriers customarily used in the compounding of solid dosage forms such as tablets and capsules. In certain embodiments, a capsule may be designed to release the active portion of the formulation at the point in the gastrointestinal tract when bioavailability is maximized and pre-systemic degradation is minimized. Additional agents can be included to facilitate absorption of the human PAC1 antibody. Diluents, flavorings, low melting point waxes, vegetable oils, lubricants, suspending agents, tablet disintegrating agents, and binders may also be employed.

Some pharmaceutical compositions comprise an effective quantity of one or a plurality of human PAC1 antibodies in a mixture with non-toxic excipients that are suitable for the manufacture of tablets. By dissolving the tablets in sterile water, or another appropriate vehicle, solutions may be prepared in unit-dose form. Suitable excipients include, but are not limited to, inert diluents, such as calcium carbonate, sodium carbonate or bicarbonate, lactose, or calcium phosphate; or binding agents, such as starch, gelatin, or acacia; or lubricating agents such as magnesium stearate, stearic acid, or talc.

Additional pharmaceutical compositions will be evident to those skilled in the art, including formulations involving human PAC1 antibodies in sustained- or controlled-delivery formulations. Techniques for formulating a variety of other sustained- or controlled-delivery means, such as liposome carriers, bio-erodible microparticles or porous beads and depot injections, are also known to those skilled in the art. See, for example, International Patent Application No. PCT/US93/00829, which is incorporated by reference and describes controlled release of porous polymeric microparticles for delivery of pharmaceutical compositions. Sustained-release preparations may include semipermeable polymer matrices in the form of shaped articles, e.g., films, or microcapsules. Sustained release matrices may include polyesters, hydrogels, polylactides (as disclosed in U.S. Pat. No. 3,773,919 and European Patent Application Publication No. EP 058481, each of which is incorporated by reference), copolymers of L-glutamic acid and gamma ethyl-L-glutamate (Sidman et al., 1983, Biopolymers 2:547-556), poly(2-hydroxyethyl-inethacrylate) (Langer et al., 1981, J. Biomed. Mater. Res. 15:167-277 and Langer, 1982, Chem. Tech. 12:98-105), ethylene vinyl acetate (Langer et al., 1981, supra) or poly-D(−)-3-hydroxybutyric acid (European Patent Application Publication No. EP 133,988). Sustained release compositions may also include liposomes that can be prepared by any of several methods known in the art. See, e.g., Eppstein et al., 1985, Proc. Natl. Acad. Sci. U.S.A. 82:3688-3692; European Patent Application Publication Nos. EP 036,676; EP 088,046 and EP 143,949, incorporated by reference.

Pharmaceutical compositions used for in vivo administration are typically provided as sterile preparations. Sterilization can be accomplished by filtration through sterile filtration membranes. When the composition is lyophilized, sterilization using this method may be conducted either prior to or following lyophilization and reconstitution. Compositions for parenteral administration can be stored in lyophilized form or in a solution. Parenteral compositions generally are placed into a container having a sterile access port, for example, an intravenous solution bag or vial having a stopper pierceable by a hypodermic injection needle.

In certain embodiments, cells expressing a recombinant antibody as disclosed herein is encapsulated for delivery (see, Invest. Ophthalmol Vis Sci 43:3292-3298, 2002 and Proc. Natl. Acad. Sciences 103:3896-3901, 2006).

In certain formulations, an antibody has a concentration of at least 10 mg/ml, 20 mg/ml, 30 mg/ml, 40 mg/ml, 50 mg/ml, 60 mg/ml, 70 mg/ml, 80 mg/ml, 90 mg/ml, 100 mg/ml or 150 mg/ml. Some formulations contain a buffer, sucrose and polysorbate. An example of a formulation is one containing 50-100 mg/ml of antibody, 5-20 mM sodium acetate, 5-10% w/v sucrose, and 0.002-0.008% w/v polysorbate. Certain, formulations, for instance, contain 65-75 mg/ml of an antibody in 9-11 mM sodium acetate buffer, 8-10% w/v sucrose, and 0.005-0.006% w/v polysorbate. The pH of certain such formulations is in the range of 4.5-6. Other formulations have a pH of 5.0-5.5 (e.g., pH of 5.0, 5.2 or 5.4).

Once the pharmaceutical composition has been formulated, it may be stored in sterile vials as a solution, suspension, gel, emulsion, solid, crystal, or as a dehydrated or lyophilized powder. Such formulations may be stored either in a ready-to-use form or in a form (e.g., lyophilized) that is reconstituted prior to administration. Kits for producing a single-dose administration unit are also provided. Certain kits contain a first container having a dried protein and a second container having an aqueous formulation. In certain embodiments, kits containing single and multi-chambered pre-filled syringes (e.g., liquid syringes and lyosyringes) are provided. The therapeutically effective amount of a human PAC1 antibody-containing pharmaceutical composition to be employed will depend, for example, upon the therapeutic context and objectives. One skilled in the art will appreciate that the appropriate dosage levels for treatment will vary depending, in part, upon the molecule delivered, the indication for which the human PAC1 antibody is being used, the route of administration, and the size (body weight, body surface or organ size) and/or condition (the age and general health) of the patient. In certain embodiments, the clinician may titer the dosage and modify the route of administration to obtain the optimal therapeutic effect.

A typical dosage may range from about 1 μg/kg to up to about 30 mg/kg or more, depending on the factors mentioned above. In specific embodiments, the dosage may range from 10 μg/kg up to about 30 mg/kg, optionally from 0.1 mg/kg up to about 30 mg/kg, alternatively from 0.3 mg/kg up to about 20 mg/kg. In some applications, the dosage is from 0.5 mg/kg to 20 mg/kg. In some instances, an antibody is dosed at 0.3 mg/kg, 0.5 mg/kg, 1 mg/kg, 3 mg/kg, 10 mg/kg, or 20 mg/kg. The dosage schedule in some treatment regimes is at a dose of 0.3 mg/kg qW, 0.5 mg/kg qW, 1 mg/kg qW, 3 mg/kg qW, 10 mg/kg qW, or 20 mg/kg qW.

Dosing frequency will depend upon the pharmacokinetic parameters of the particular human PAC1 antibody in the formulation used. Typically, a clinician administers the composition until a dosage is reached that achieves the desired effect. The composition may therefore be administered as a single dose, or as two or more doses (which may or may not contain the same amount of the desired molecule) over time, or as a continuous infusion via an implantation device or catheter. Appropriate dosages may be ascertained through use of appropriate dose-response data. In certain embodiments, the antibodies can be administered to patients throughout an extended time period. Chronic administration of an antibody minimizes the adverse immune or allergic response commonly associated with antibodies that are not fully human, for example an antibody raised against a human antigen in a non-human animal, for example, a non-fully human antibody or non-human antibody produced in a non-human species.

The route of administration of the pharmaceutical composition is in accord with known methods, e.g., orally, through injection by intravenous, intraperitoneal, intracerebral (intra-parenchymal), intracerebroventricular, intramuscular, intra-ocular, intraarterial, intraportal, or intralesional routes; by sustained release systems or by implantation devices. In certain embodiments, the compositions may be administered by bolus injection or continuously by infusion, or by implantation device.

The composition also may be administered locally via implantation of a membrane, sponge or another appropriate material onto which the desired molecule has been absorbed or encapsulated. In certain embodiments, where an implantation device is used, the device may be implanted into any suitable tissue or organ, and delivery of the desired molecule may be via diffusion, timed-release bolus, or continuous administration.

It also may be desirable to use human PAC1 antibody pharmaceutical compositions ex vivo. In such instances, cells, tissues or organs that have been removed from the patient are exposed to human PAC1 antibody pharmaceutical compositions after which the cells, tissues and/or organs are subsequently implanted back into the patient.

In particular, human PAC1 antibodies can be delivered by implanting certain cells that have been genetically engineered, using methods such as those described herein, to express and secrete the polypeptide. In certain embodiments, such cells may be animal or human cells, and may be autologous, heterologous, or xenogeneic. In certain embodiments, the cells may be immortalized. In other embodiments, in order to decrease the chance of an immunological response, the cells may be encapsulated to avoid infiltration of surrounding tissues. In further embodiments, the encapsulation materials are typically biocompatible, semi-permeable polymeric enclosures or membranes that allow the release of the protein product(s) but prevent the destruction of the cells by the patient's immune system or by other detrimental factors from the surrounding tissues.

The following examples, including the experiments conducted and the results achieved, are provided for illustrative purposes only and are not to be construed as limiting the scope of the appended claims.

Example 1 PAC1 Antibodies

A. Generation of Anti-PAC1 Antibodies

Fully human antibodies were generated through immunization of XENOMOUSE animals with the PAC1 extracellular domain protein, DNA tagged with a T-cell epitope tag, L1.2 cells expressing full-length human PAC1, and other hPAC1 antigens using standard methods, e.g., substantially as detailed in US patent publication US 2010-0172895 A1.

B. Screening of Anti-PAC1 Antibodies

Hybridoma supernatants were screened for binding to PAC1 and also for functional antagonist activity in an assay detecting their ability to block generation of cAMP by activation of PAC1 with either PACAP (e.g., PACAP-27 or PACAP-38) or a selective, exogenous peptide ligand (Maxadilan), and then counter-screened against the related receptors VPAC1 and VPAC2. Those supernatants with desirable function and selectivity were sequenced and cloned, expressed recombinantly, purified, and tested again for function and selectivity using standard methods, e.g., substantially as detailed in US patent publication US 2010-0172895 A1, incorporated herein by reference.

C. Selectivity of PAC1 Agonists

Experiments were performed to assess the activity and selectivity of three PAC1 agonists (PACAP, VIP and Maxadilan) against the related receptors PAC1, VPAC1 and VPAC2.

Example 2 Activity of PAC1 Specific Blocking Monoclonal Antibodies in cAMP Functional Assay

A. Activity of Anti-PAC1 Antibodies

Selected hPAC1 antibodies as described herein were screened in an in vitro PAC1 mediated cAMP assay to determine intrinsic potency. The assay employed SH-SY-5Y, a human neuroblastoma cell line endogenously expressing hPAC1 (Biedler, J. L., et al., 1978, “Multiple neurotransmitter synthesis by human neuroblastoma cell lines and clones”. Cancer Res. 38 (11 Pt 1): 3751-7; Lutz, E. M., et al., “Characterization of novel splice variants of the PAC1 receptor in human neuroblastoma cells: consequences for signaling by VIP and PACAP.” Mol Cell Neurosci 2006; 31:193-209), and several cells lines expressing recombinant PAC1, VPAC1 & VPAC2 constructs having the following accession numbers: human PAC1 (hPAC1): NM_001118.4; hPAC1 short (hPAC1 with amino acid residues 89-109 deleted (range used: 1-88, 110-468)): NM_001199637.1; cyno PAC1: XM_005549858.1; rat PAC1: NM_133511.2; mouse PAC1: NM_001025372.2; human VPAC1 (hVPAC1): NM_004624.3; human VPAC2 (hVPAC2): NM_003382.4; rat VPAC2: NM_017238.1; mouse VPAC2: NM_009511.2.

CHO-Trex-rat and mouse VPAC2R stable cell lines were grown in Basal Media: F12 (Invitrogen 11765-047), P/S/G: 1× (Invitrogen 10378016), Heat inactivated FBS: 10% (Invitrogen 10100147), Blasticidin: 5 ug/ml (Invitrogen 821001) and Hygromycin: 400 ug/ml (Invitrogen 10687010). The cells were induced with Tetracyclin (Sigma 87128): 3.5 μg/ml, add 24 hours before assay. hPAC1-CHO-K1 cells (Perkin Elmer; ES-272-A) were grown in Ham's F12 (Invitrogen 11765-047), 10% FBS (Invitrogen 10099-141), Pen-strep: 1× (Invitrogen 15140122), 400 μg/ml G418 (Stock: 50 mg/ml=>8 ml/L media) (Invitrogen 10131027), 250 μg/ml Zeocin (Stock: 100 mg/ml=>2.5 ml/L media) (Invitrogen R25005). VPAC1/CHO-CRE-BLA (Invitrogen; Agonist:VIP) cells were grown in Dulbecco's modified Eagle's medium (DMEM) (Gibco Cat#11965), Dialyzed FBS: 10% (Invitrogen 26400044), NEAA: 1× (Invitrogen 11140-050), Pen/Strep: 1× (Invitrogen 15140122), HEPES (pH 7.3): 25 mM (Invitrogen 15630130). VPAC2/CHO-CRE-BLA (Invitrogen; Agonist:VIP) cells were grown as described above for the VPAC1 cells, with the addition of Blasticidin: 5 μg/ml (Invitrogen R21001) and Geneticin: 500 μg/ml (G418) (Invitrogen 10131027). SK-N-MC cells were grown in MEM (Invitrogen 11095-072), 10% FBS (Invitrogen 10099-141), 1×NEAA (Invitrogen 11140-050), 1× Sodium pyruvate (Invitrogen 11360070), 1×glutamine/pen/strep (Invitrogen 10378016). L6 cells were grown in Dulbecco's modified Eagle's medium (DMEM) (Gibco Cat#11965), 10% Fetal Bovine Serum (Gibco Cat#10099-141), 1× Glutamine/Pen/Strep (Gibco Cat#10378-016).

The cells were grown under the conditions described above and harvested at 80-90% confluence. The cells were dissociated with VERSENE (1:5000, Invitrogen, 15040-060) for SHSY5Y cells; with 0.05% Trypsin-EDTA (1×), Phenol Red (Invitrogen, 25300054), and were then centrifuged in a Beckman GS-6R unit at 1000 rpm for 5 minutes at 4° C. The pellets were resuspended with cell freezing medium (Invitrogen, 12648010). The cells were then counted using a Z1 Coulter Particle Counter and adjusted to desired concentration (5E6/ml or 2E6/ml) and aliquots were stored at −80° C. or in liquid nitrogen until use. Concentrations for PAC1 cells, hVPAC1/2 CHO were 4K/10 μl; the others at 2K/10 μl; for SKNMC and L6, the concentration was 1K/10 μl.

The LANCE Ultra cAMP assay kit (PerkinElmer, Boston, Mass.) was used in the screening. The assays were performed in triplicate in white Optiplates half-area 96-well plates (Costar 3642) in a total volume of 40 μL. Briefly, vials of frozen cells were thawed by incubating at 37° C. in a water bath. The thawed cells were washed once with assay buffer (F12, 0.1% BSA, 1 mM IBMX) and the cell concentration was adjusted to 2K/10 μl. The cell suspension was distributed in 10 μl aliquots into the 96 half area white plates. Five microliters of antagonist (e.g., an anti-PAC1 antibody as described herein) were then added, and the samples were incubated for 30 minutes at room temperature with gentle shaking. Five microliters of agonist (e.g., PACAP38) was then added, and the samples were incubated for an additional 15 minutes, again at room temperature, with gentle shaking. Ten microliters of 4× Eu-cAMP tracer working solution and ten microliters of 4× ULight-anti-cAMP working solution were then added and the samples were incubated an additional 45 minutes at room temperature.

The samples were analyzed on EnVision instrument at Em665/615 nM. The data were processed by GraphPad Prism software version 5/6 (GraphPad Inc., La Jolla, Calif.) to show POC (percent of control) as a function of the tested antagonist anti-PAC1 antibody concentration, and were fitted with standard nonlinear regression curves to yield IC50 values. POC was calculated as follows:

${POC} = {100 \times {Em}\; 665\mspace{14mu}{of}\mspace{14mu}\frac{\begin{matrix} {{{Agonist}\mspace{14mu}{response}\mspace{14mu}{with}\mspace{14mu}{antagonist}} -} \\ {{cell}\mspace{14mu}{response}\mspace{14mu}{without}\mspace{14mu}{agonist}\mspace{14mu}{and}\mspace{14mu}{antagonist}} \end{matrix}}{\begin{matrix} {{{Agonist}\mspace{14mu}{response}\mspace{14mu}{without}\mspace{14mu}{antagonist}} -} \\ {{cell}\mspace{14mu}{response}\mspace{14mu}{without}\mspace{14mu}{agonist}\mspace{14mu}{and}\mspace{14mu}{antagonist}} \end{matrix}}}$

All antibodies described herein and tested in the assay had IC50 activity between about 0.1 nM and about 200 nM; most had activity between 0.1 nM and 100 nM. Similar experiments were performed using recombinant cells expressing cynomolgus PAC1 and rat cells expressing rat PAC1 as described above. IC50 obtained using human and cynomolgus PAC1s were similar, whereas the tested antibodies did not appear to uniformly cross-react well with rat PAC1. In addition, cells expressing related receptors hVPAC1 (CRE-Bla-CHO-K1/Invitrogen) and hVPAC2 (-Bla-CHO-K1/Invitrogen) were used to further assess the selectivity of the tested antibodies. None of the tested antibodies had significant inhibitory activity against hVPAC1 or hVPAC2 over the range tested (IC50 was >10,000 nM in all cases). Exemplary data are shown in Table 8, below.

The differences in IC50 between human PAC1 and human VPAC1 and VPAC2 receptors illustrates the high selectivity of these antibodies for the PAC1 over related receptors.

Example 3 Radioligand Binding Assays for Ki Determination of Receptor Blocking Antibodies

¹²⁵I-labeled PAC-1 antibodies (for PAC1 binding assay) or ¹²⁵I-labeled PEG-PACAP38 (for PACAP38 binding assay), both obtained from Perkin Elmer (Billerica, Mass.), and cell membranes prepared from hPAC-1 AequoScreen CHO (PerkinElmer Life and Analytical Sciences, Boston, Mass.) were used for radioligand binding experiments in the presence of various concentrations of the test antibodies to determine the corresponding Ki values.

Cell Membrane Preparation

Cells were grown to confluency in 40×T225 flasks in Ham's F12, 10% FBS, 100 μg/ml streptomycin, 400 μ/ml G418 (receptor expression selection) and Zeocin (Aequorin expression selection). Flasks were washed 1× with Ca/Mg free PBS. PBS was removed completely. 5 ml VERSENE was added to each flask and waited about 5 min. The flasks were tapped on the side and all the cells were dislodged. VERSENE/cell suspension from all flasks were transferred to 50 ml conical tubes and placed on ice. To collect any remaining cells, flasks were rinsed with ice cold PBS, without Ca/Mg, with protease inhibitors and solution was added to the cells in tubes. Tubes were spun down at 1000 rpm for 10 min. Pellets were stored at −80° C.

The day of the membrane preparation, the cell pellets were weighed and dissolved on ice. Pellets were resuspended in (10 ml/gram of pellet) 10 mM TrisHCl, pH7.4, 1 mM EDTA, Roche protease inhibitors (1 tablet/50 ml) and homogenized by 30 strokes with the motorized dounce homogenizer. Cell homogenates were centrifuged at 2500 rpm (˜1000 g) for 10 min at 4° C. Supernatants were transferred to a Beckman centrifuge tube and keep on ice. Pellets were rehomogenized with 15 ml of the buffer and the spin step was repeated. Both supernatants were combined and centrifuged at 48,400 g for 30 min. Pellets were resuspended in 15 ml buffer and sheared through an 18G syringe to break up the pellet. Pellets were Homogenized by 20 strokes and centrifuged 48,400 g for 30 min. Pellets were resuspended in ˜6 ml of PACAP Binding buffer without BSA (20 mM Tris HCl, 5 mM MgSO4+Protease Inhibitors). Pellets were resuspended using an 18G syringe, dounce homogenized, aliquoted and stored at −70° C. Total membrane protein concentration was determined with a Microplate BCA Protein Assay (Pierce).

Binding Assay

The PAC1 binding assay was set up at room temperature in 96-well plates containing: 120 μl binding buffer (20 mM Tris-HCl, pH 7.5, 5.0 mM MgSO4, 150 mM NaCl, 0.1% BSA (Sigma), 1 tablet of Complete TM/50 ml buffer (a protease inhibitor)); 10 μl test compound (20×); 50 μl human PAC1 CHO membrane suspension (0.2 μg per well); and 20 μl of either ¹²⁵I-PAC-1 antibody (10×; for the PAC1 binding assay) or ¹²⁵I-PEG-PACAP 38 (10×; for PACAP38 binding assay).

Non-specific binding was determined by adding 10 μl of (20×) 20 μM PACAP 6-38 into designated plates. The plates were incubated at room temperature for 2 hours with shaking at 60 rpm, and then the contents of each well were filtered over 0.5% polyethyleneimine (PEI)-treated (for at least two hours) GF/C 96-well filter plates. The GF/C filter plates were washed five times with ice-cold 50 mM Tris, pH 7.5 and dried in an oven at 55° C. for 1 hour. The bottoms of the GF/C plates were then sealed. 40 μl Microscint™ 20 was added to each well, the tops of the GF/C plates were sealed with TopSeal™-A (a press-on adhesive sealing film), and the GF/C plates were counted with TopCount NXT (Packard). The data were analyzed using Prizm (GraphPad Software Inc.)

Exemplary data showing the Ki values obtained as described above are shown in Table 9, below. Data from the PAC1 binding assay are shown with the indicated ¹²⁵I-labeled PAC-1 antibodies in different columns, and test antibodies as shown in different rows. Samples from different production lots were run with some of the test antibodies, as shown (01A, 26A, 39A). The results indicate that the tested anti-PAC1 antibodies which have biological activity in the cAMP assay described in Example 2 compete with binding of an agonist of PAC1 (¹²⁵I-labeled PEG-PACAP38), and also cross-compete with one another for the same or similar epitope on hPAC1.

Example 4 Binding Kd Measured by Kinexa

A. Experiments Using Whole Cells Expressing hPAC1.

Binding of anti-Pac1 antibody with CHOK1/huPac1 cells were tested on KinExA. Briefly, UltraLink Biosupport (Pierce cat#53110) was pre-coated with goat-anti-huFc (Jackson Immuno Research cat#109-005-098) and blocked with BSA. 10 pM, 30 pM, 100 pM, and 300 pM of anti-Pac1 antibody was incubated with various density (1.7×101-9×106 cells/mL) of CHOK1 cells expressing huPac1 in medium F12 containing 1% FBS and 0.05% sodium azide. Samples containing anti-Pac1 antibody and whole cells were incubated with rotation at room temperature for 4 hours before 5-minute 220-g centrifugation at 4° C. to separate the whole cells and anti-Pac1 antibody-cell complexes from unbound anti-Pac1 antibody. The supernatants containing free anti-Pac1 antibody were filtered through 0.22 μm filter before loading to the goat-anti-huFc-coated beads on KinExA. The amount of the bead-bound anti-Pac1 antibody was quantified by fluorescent (Alexa Fluor 647) labeled anti-huIgG (H+L) antibody (Jackson Immuno Research cat#109-605-088). The binding signal is proportional to the concentration of free anti-Pac1 antibody in solution at each cell density. Equilibrium dissociation constant (KD) was estimated by n-curve analysis in KinExA™ Pro software (Sapidyne Instruments, Inc., Boise, Id.).

B. Experiments Using hPAC1 Extra-Cellular Domain (ECD; hPAC1 1-135).

Binding of anti-Pac1 Abs with huPac1(1-135)::6×His was tested on KinExA. Briefly, UltraLink Biosupport (Thermo Fisher Scientific cat#53110) was pre-coated with huPac1 (1-135)::6×His and blocked with BSA as described above. 30, 100, and 300 pM of Ab were incubated with various concentrations of huPac1 (1-135)::6×His at room temperature for at least 8 hours before run through the huPac1 (1-135)::6×His-coated beads. The amount of the bead-bound Ab were quantified by fluorescent (DyLight 649) labeled goat anti-huIgG (H+L) antibody (Jackson Immuno Research cat#109-495-088). The binding signal is proportional to the concentration of free Ab at binding equilibrium. Equilibrium dissociation constant (KD) was obtained from nonlinear regression of the competition curves using a one-site homogeneous binding model (KinExA™ Pro software).

A summary of the equilibrium dissociation constants for the tested samples binding with CHOK1/huPac1 cell and huPac1 (1-135)::6×His are shown in Table 10, below (average followed by (range)).

Example 5 Platelet Phagocytosis Assay

To address any potential Fc gamma receptor induced platelet depletion, a subset of the antibodies described herein was tested in a Phagocytosis Assay.

A. Preparation of Peripheral Blood Leukocytes (PBL) and Platelets

Both human and cynomolgus platelets were prepared as previously described (Semple, J. W., et al., Blood (2007) 109: 4803-4805). In brief, whole blood samples from healthy cynomolgus donors were centrifuged at 170×g for 15 minutes with no braking. Platelet-rich plasma (PRP) was collected from the top layer. The bottom layers of the sample were centrifuged at 2000×g for 10 minutes to obtain the platelet-poor plasma (PPP) layer and buffy coat. Platelets in the PRP fraction were labeled with 20 μM Cell Tracker Green CMFDA for 30 minutes at room temperature. Labeled platelets were washed with PBS, resuspended in RPMI-1640 with 10% FBS, and adjusted to a concentration of 1×10⁸ cells/mL. PBL were prepared from the buffy coat obtained from the same donor. Erythrocytes were lysed with BD Pharm-lyse following the protocol provided by the vendor. After lysing, PBL were washed twice with RPMI-1640 with 10% FBS and the final concentration was adjusted to 5×10⁶ cells/ml.

B. Phagocytosis Assay

The phagocytosis reaction was initiated by incubating 100 μL each of CMFDA-labeled platelets and PBMC with test articles in the dark. After six hours of incubation, the reaction was stopped by placing the plates on ice. Extracellular fluorescence was quenched by incubating 2 minutes with 0.1% trypan blue. After washing twice with ice cold PBS, the cells were incubated with propidium iodide and anti-CD14 for 30 minutes at 4° C. After washing, the cells were analyzed by a BD LSRII Flow Cytometer (FIG. 2). Based on previous experiences, monocytes phagocytosing platelets have CMFDA median fluorescence intensity values at least 2-fold or higher than negative controls (either a-SA or a-DNP) (2).

Exemplary data are shown in Table 11, below. The results show that none of the assayed aglycosylated IgG1 variants (antibodies ending with “B” or “C”, although only the “B” were tested in this study) activated platelets in human or cynomolgus whole blood when tested at antibody concentrations up to 14 mg/mL. Similarly no effect was seen on in vitro platelet phagocytosis up to and including the highest concentration tested (3 mg/ml). No in vitro neutrophil activation was noted at any concentration tested.
